Richard Grenville 58c0ecec40 Feature #80: D-Bus support
- Add D-Bus support. Currently 7 methods are available: "reset" (same as
  SIGUSR1), "list_win" (list the windows compton manages), "win_get"
  (get a property of the window), "win_set" (set a property of the
  window), "find_win" (find window based on client window / focus),
  "opts_get" (get the value of a compton option), and "opts_set" (set
  the value of a compton option), together with 4 signals: "win_added",
  "win_destroyed", "win_mapped", "win_unmapped".

- D-Bus support depends on libdbus.

- As there are many items and my time is tight, no much tests are done.
  Bugs to be expected.

- Create a new header file `common.h` that contains shared content.

- Fix some bugs in timeout handling.

- Update file headers in all source files.

- Re-enable --unredir-if-possible on multi-screen set-ups, as the user
  could turn if off manually anyway.

- Check if the window is mapped in `repair_win()`.

- Add ps->track_atom_lst and its handlers, to prepare for the new
  condition format.

- Known issue 1: "win_get", "win_set", "opts_get", "opts_set" support a
  very limited number of targets only. New ones will be added gradually.

- Known issue 2: Accidental drop of D-Bus connection is not handled.

- Known issue 3: Introspection does not reveal all available methods,
  because some methods have unpredictable prototypes. Still hesitating
  about what to do...

- Known issue 4: Error handling is not finished yet. Compton does not
  always reply with the correct error message (but it does print out the
  correct error message, usually).

Richard Grenville e60fe72dcb Bug fix #75: --invert-color-include not working & others
- Fix a small bug that breaks --invert-color-include if no other
  blacklists are present. Thanks to MaskRay and xiaq for reporting.

- Disable --unredir-if-possible for multi-screen setups.

- Fix a bug that causes --no-fading-openclose to have no effect in some
  cases. Add w->in_openclose to keep track of window open/close state.
2013-01-13 13:44:05 +08:00
Richard Grenville 2165c42d27 Feature #75: Invert window color
- Add window color inversion (--invert-color-include). It means 2-3
  times extra painting, so performance issues are likely to appear.  I
  hope I could find a faster way to invert colors.

- Rename some functions.

- Fix update of some window properties after window type/data change.
  Hopefully this will be helpful for #73.

- Split win_build_picture() from win_blur_background().

- Correct memory leak of ps->focus_blacklist during reinitialization.

- Add win_upd_t and win_upd_run(), to reduce duplicate window property
  updates. But is unused right now.

- Limited tests are done overall. Bugs to be expected.
2013-01-12 22:44:46 +08:00
Richard Grenville 57c5854fd0 Improvement: Use select() for main loop
- Back to using select() for main loop. Thus we are not longer relying
  on libevent.

- Add generic timeout system (untested) to prepare for D-Bus support.

- Drop troff man pages. Revise Makefile to improve documentation
  building, fix double LDFLAGS inclusion, and re-add -lrt. This turns
  asciidoc into a build time dependency.

- Change fading time calculation.

- Add --logpath and ostream_reopen() for debugging with -b.

- Drop unused lceil_ntimes() and other helper functions.

- Only very limited tests are done. Bugs to be expected.
2013-01-11 21:31:02 +08:00
Richard Grenville 7188054825 Bug fix #77 incorrect border_width handling & #73 window data issue
- (Hopefully) fix all incorrect handling of w->a.border_width in compton
  (#77). Thanks to baskerville for reporting.

- Attempt to fix #73 by correcting a mistake that window data is fetched
  from the wrong function. Thanks to zakkak.

- Add git commit/tag detection to Makefile for automatic versioning.

- Change -lGL linking order, to fix a segmentation fault caused by
  something in nvidia-drivers under FreeBSD, mentioned in #74. Thanks
  for the report from DachiChang.

- Link to -levent_core instead of -levent in Makefile. We might move to
  libev soon, though.

- Increase SWOPTI_TOLERANCE to handle the extraordinary delay of
  kqueue() under FreeBSD. Thanks for DachiChang's report.

- Add helper function dump_drawable() for debugging.

- Replace XInternAtom() calls with get_atom().

- Remove -lrt as it's unneeded.
2013-01-09 20:41:18 +08:00
Richard Grenville 3521f10a97 Improvement #74: Use libevent for main loop
- Use libevent for main loop. I will explain the reasons in #56 later.
  The preferred libevent version is 2.x, yet 1.4.x should work as well.

- As a result, compton now should build fine on *BSD. Thanks to
  DachiChang for the FreeBSD build issue report.

- Another consequence is we now use microsecond-level timing all the
  way. Nanosecond-level code will be dropped soon. Start using long
  instead of unsigned long to represent time in milliseconds, as both
  can't hold the full epoch time in ms, anyway, and a signed type
  requires less care in subtraction. Wrap the epoch time in ms to 15
  days.

- Fix broken NO_VSYNC_DRM and NO_VSYNC_OPENGL compile-time options.

- Use git revision number for versioning in Makefile, and other small
  improvements.

- Reorganize struct _win. Drop unused w->damaged_sequence. w->damaged is
  turned to bool.

- Add type and format to winprop_t, as preparation for the new condition
  format.

- Add w->shadow_force and w->focus_force, to prepare for D-Bus support.

- Rename wid_get_prop() to wid_get_prop_adv() with more options. Add
  wrapper function wid_get_prop().

- Add some extra helper functions, for D-Bus support later.

- Make some functions return a bool value to indicate if it's
  successful.

- Modify add_win(), use a static const structure to initialize the new
  struct _win.

- Add some helper macros, like printf_err(f)(q). Make some errors fatal.

- Rename some types, constants, and functions. Code clean-up.

- Check for time disorder in paint_preprocess() when calculating fading
  steps.

- Rename evpoll() to swopti_handle_timeout(), and partially rewrite it.

- Make -h / --help legal.

- Known issue: compton segfaults on FreeBSD with nvidia-drivers, unless
  NO_VSYNC_OPENGL is used. Will look into it later. Thamls to DachiChang
  for reporting.

Richard Grenville 75aec17a85 Misc: Documentation update
Update man page and README.
2012-12-18 22:04:22 +08:00
Richard Grenville 1bfe21efb5 Improvement: Dynamic blur strength & improved frame blur performance
- Remove the region expansion design in win_blur_background(). I must be
  sleep-walking when I wrote that!

- Improve performance of blurring when a window is opaque but its frame
  is transparent.

- Adjust blur strength according to window opacity.
  --blur-background-fixed restores the old behavior.

- Add "use_offset" parameter to a few functions for convenience. Code
  clean-up.
2012-12-15 20:07:45 +08:00
Richard Grenville 22cabf7c89 Feature #69: Blur window background
- Add window background blur support (--blur-background &
  --blur-background-frame), with X Render convolution filter.
  The performance sucks. The performance when the window is opaque but
  frame is transparent could be improved, but there are two possible
  ways and I'm hesitating.

- Known issue: The blurring effect looks very ungraceful during fading.
  I could partially fix the problem, but it probably isn't easy to fix
  it completely.
2012-12-14 20:32:46 +08:00
Richard Grenville a77aaf0718 Misc: Code cleanup
- Move some long functions to ./src/compton.c .

- Fix a small potential issue in win_set_focused() when a window with
  neither leader nor client window is focused.

- Add DEBUG_LEADER.
2012-12-12 12:47:17 +08:00
Richard Grenville 848687b853 Feature #65: Auxiliary window detection
- Add auxiliary window detection (--detect-transient &
  --detect-client-leader). Thanks to SmilingHorse for inspiring me. The
  implementation is not too speed-efficient, and bugs are to be
  expected.

- Known issue: auxiliary window detection may not work too well with
  windows that are never mapped, for example as client leader.
2012-12-12 12:01:51 +08:00
Richard Grenville 33171e8933 Feature: Wintype-based focus exclusion
- Add "focus" to the wintypes settings in compton.conf, to mark windows
  of certain window types to be always focused. Replaces the ugly
  is_normal_win().

- Add a ON/OFF/UNSET switch_t type, but it's unused currently.

- Mark client_win if the window client detection hasn't been performed
  when we detect WM_STATE's presence in ev_property_notify(), for
  performance.
2012-12-10 10:38:28 +08:00
Richard Grenville 7d70f3dc13 Bug fix #68: Second attempt to fix client window detection
- Attempt to fix client window detection when WM_STATE property is not
  yet set when the window is mapped. Thanks to kinclma1 for reporting.

- Apply stricter checks for whether window is mapped in
  determine_evmask() and win_mark_client().
2012-12-08 11:10:08 +08:00
Richard Grenville 812ba93516 Bug fix #68: Possible fix for failure in client window detection
- Note I'm not in the best state today (bad cold & sleep-deprived). This
  commit is likely to introduce bugs.

- Attempt to fix client window detection failures happening when compton
  searches for client window before it's ready.

- Fix build failure with <libpcre-8.20. Thanks to @pvanek for reporting
  in #51.

- Move client window detection to a new function win_recheck_client().

- Add win_unmark_client(), which unmarks a client window.

- Rename a few functions.

- Split fetching of values of type-Window properties to a new function
  wid_get_prop_window().

- Add extra safety checks and assert calls to various functions, to
  expose potential bugs.

- Fix a memory leak that w->role is not freed on window destruction.
2012-12-07 23:06:15 +08:00
Richard Grenville a7189263e1 Feature: WM_WINDOW_ROLE matching
- Add support of matching WM_WINDOW_ROLE value. Thanks to Vladimir A.
  Pavlov!

- Thanks to Vladimir A. Pavlov for reporting the issues caused by
  missing client window, fixed in the last commit!

- Fix a memory leak in wid_get_text_prop() and wid_get_name(). Xlib
  documentation did not mention how to free the value XGetTextProperty()
  returns, so my fix could lead to troubles.

- Set focus out in unmap_win(), and add w->leader, to prepare for
  subsidiary window detection.

- Abstract update of a single string window property to
  win_get_prop_str().

- Change wid_get_name() to rely on wid_get_text_prop() as much as
  possible.

- Correct a typo in win_get_prop_str() that could cause unnecessary
  update of shadow state and window focus.
2012-12-05 18:23:35 +08:00
Richard Grenville 983803aa9f Bug fix: Dynamic inactive dim & client window changes
- Make inactive_dim opacity change according to window opacity by
  default, so it looks better when fading. --inactive-dim-fixed restores
  the old behavior.

- Make client window default to the window itself. Add w->wmwin to
  represent whether the window looks like a WM window instead. A side
  effect is, the window type of WM windows are changed from unknown to
  normal, making it necessary to use --mark-wmwin-active to avoid
  considering them unfocused.

- Add check of PointerRoot to recheck_focus() to avoid BadWindow errors
  when the root window is focused.

- Add a few macros to simplify debugging code.

- Add DEBUG_FRAME.
2012-12-05 15:28:37 +08:00
Richard Grenville 9e66fd5b3f Misc: Man page updates
Update Asciidoc man page.
2012-12-04 22:34:24 +08:00
Richard Grenville 72c18b6219 Feature #65: --focus-exclude
- Add --focus-exclude, which should be used with a list of conditions to
  set certain windows to always be considered focused.

- Change focus determination process, with a newly added w->focused_real
  that reflects whether the window is actually focused, while w->focused
  represents whether compton considers it focused. The primary
  difference is now when a window considered focused because of
  --mark-wmwin-focused or --mark-ovredir-focused receives a FocusOut
  event, it's still considered focused by compton.

- Change opacity target and dim state calculation so that it's done at
  most once every paint.

- Split window opacity property fetching from calc_opacity() to a new
  function win_update_opacity_prop().

- Silence a warning in wid_get_prop_wintype().

- Rename a few functions. Code clean-up.

- My time is very limited currently, few tests are done, so this commit
  may very well introduce bugs.

- Known issue: Dim picture opacity does not change based on window
  opacity, causing somehow annoying effects when a window fades off.
2012-11-28 12:07:58 +08:00
Richard Grenville 0f851b17a2 Bug fix: --use-ewmh-active-win causes wrong focus state in Awesome
- Fix a bug that causes wrong focus detection result in Awesome and
  maybe other window managers, when --use-ewmh-active-win is enabled and
  _NET_ACTIVE_WINDOW changes before the newly-focused window is mapped.

- Fix a typo that causes more than one window to stay focused after a
  window destruction with --use-ewmh-active-win.

- Fix a bug that find_clientwin() incorrectly returns a window when
  window ID 0 is passed to it.

- Check for window ID 0 in update_ewmh_active_win().
2012-11-27 08:41:55 +08:00
Richard Grenville 9ca20e7e32 Bug fix: Wrong file path being displayed on config file parsing error
- Fix a bug that causes wrong file path being displayed on configuration
  file parsing error.

- Continue dropping unused parameters and silence clang warnings.

- Add conky shadow exclusion rule to compton.sample.conf.
2012-11-21 09:15:49 +08:00
Richard Grenville e912fcde7b Feature #51: Re-initialize when SIGUSR1 is received
- Create a session_t structure, to get rid of most global variables and
  let information pass in/out mostly through parameters. Huge changes,
  so bugs may very well appear. I'm worried about resource leakages, in
  particular.

- Add gcc attributes on various functions.

- Add Doxygen configuration.

- Replace much Xlib Bool with C99 bool.

- Add and adjust some comments.

- Drop unused parameters from some functions.

- Cache default Visual and Depth, mainly to shorten code.

- Rename some types, variables, and functions.

- Add win_ev_stop() and set_ignore_next() for convenience.

- Modify wid_get_prop_wintype() and wid_get_opacity_prop() to use
  wid_get_prop().

- Rename --respect-attr-shadow to --respect-prop-shadow.

- Fix a memory leak in --respect-prop-shadow.

- Many other small changes.
2012-11-19 11:44:58 +08:00
Richard Grenville a92c2bd808 Misc: Code cleanup
- Form a function ev_window_name() for all window name detection in
  debugging code.

- Add unredir-if-possible to configuration file options.
2012-11-14 21:34:51 +08:00
Richard Grenville 09c10c227c Misc: Documentation updates
Update README.md and two Asciidoc man pages. Remove the options and

Richard Grenville 62ea373ee5 Merge branch 'master' into richardgv-dev
Conflicts:
	bin/compton-trans

- Add some explaination in README.md.

- Rename CMakeLists.txt to _CMakeLists.txt to avoid confusion.
2012-11-14 18:46:26 +08:00
Richard Grenville fd9c9ba38d Misc: compton-trans: Allow reading opacity from positional arguments
- compton-trans: Allow reading opacity value from positional arguments,
  like the version in master branch.

- compton-trans: Quit when meeting an unrecognized option.
2012-11-14 18:17:32 +08:00
Richard Grenville ce7f686f9e Misc: compton-trans: Performance optimization
Reduce abundant calls to xwininfo in compton-trans further. Helpful for
performance but you can't expect too much from a bash script anyway.
2012-11-11 13:02:14 +08:00
Richard Grenville aaeafbd19d Bug fix: Client window event mask not restored in map_win()
- Fix a bug that client window event masks are not restored in
  map_win(), causing further property changes to be ignored, for
  example.

- Misc changes.
2012-11-10 11:41:01 +08:00
Richard Grenville 59e54b0665 Feature: Unredirect windows when there's a fullscreen window
- Optionally unredirect windows when there's a fullscreen opaque window on
  the top of the stack (--unredir-if-possible). Experimental. Known
  issues:

  * Screen flickers when redirecting/unredirecting windows.
    --paint-on-overlay seemingly minimizes it (Thanks for hints from
	mutter), but still noticeable.

  * It probably does not play well with vdpau in some cases.

- A debug option DEBUG_REDIR is added.

- Fix a bug that reg_ignore are not expired when a CirculateNotify is
  received.

- Add extra safe guards in some places, which could be bad for
  performance.

- Remove some abundant code.
2012-11-09 22:16:41 +08:00
Richard Grenville e924976b28 Feature #16: _COMPTON_SHADOW window property support
- Add support for reading _COMPTON_SHADOW property from windows
  (--respect-attr-shadow). Presently the only defined behavior is, if
  _COMPTON_SHADOW is set on the highest ancestor below root window of a
  window (usually the WM frame), it's format is 32-bit, type is CADINAL,
  value is 0, the window will not get a shadow. The format and behavior
  could change in the future without prior notification.

- Fix an issue in fork_after() that may cause some streams to remain
  open. My mistake.

- Attempt to reduce determine_shadow() calls from map_win() by
  separating some raw handler functions out.
2012-11-09 11:41:21 +08:00
Richard Grenville b47205db08 Misc: Update CMakeLists.txt
Update CMakeLists.txt to support Asciidoc man page / HTML doc

Christopher Jeffrey c883cdec3e compton-trans: add error handling. better option parsing. 2012-11-08 09:21:57 -06:00
Richard Grenville 08ca5b4d1e Bug fix #62: Rewrite a part of compton-trans
Rewrite a part of compton-trans in order to provide more friendly
error messages, to support window title that contains spaces, and to
limit the number of xwininfo calls to a constant. Not much tests are
done, and I don't know bash well, so bugs could very well exist.
2012-11-08 22:37:31 +08:00
Richard Grenville 56ce896feb Bug fix: Shape update of opaque windows not handled correctly
- Fix a bug that causes rendering issues if a opaque window changes
  shape.

- Remove abundant handling code in paint_preprocess() when generating
  border_size as border_size() is no longer relying on
  XFixesCreateRegionFromWindow() right now by default.

- Add extra code to print backtrace in DEBUG_ALLOC_REG.

- Move initialization of fade_time closer to first paint.
2012-11-08 19:45:39 +08:00
Richard Grenville 357bf94efc Bug fix: Window rendered incorrectly if has no border with -e
- Fix a bug that window content and some borders are not rendered if the
  window has no border on particular sides when -e (frame-opacity) is
  enabled, introduced in 66d3f30978. Just as what I said in the commit
  message of the commit, "bugs are to be expected". :-S

- Fix a potential segfault in win_match().

- Slightly update CPackConfig.cmake to add dependency to libdrm.
2012-11-06 11:37:29 +08:00
Richard Grenville c76d0fc150 Misc: Asciidoc man page update
- Add man page for compton-trans in Asciidoc format.

- Add description of --use-ewmh-active-win to compton man page.
2012-11-05 18:06:31 +08:00
Richard Grenville b15d40ec09 Bug fix #61: Silence a warning
- Silence a FORTIFY_SOURCE warning. Thanks to @smlx for reporting.

- Add -O2 -D_FORTIFY_SOURCE=2 to default CFLAGS in Makefile.

- Use a cleaner way to resolve the writing-to-freed-memory issue
  mentioned in last commit.
2012-11-04 19:44:14 +08:00
Richard Grenville dc04a7d8ca Improvement: Add EWMH _NET_WM_ACTIVE_WINDOW support
- Add support for using _NET_WM_ACTIVE_WINDOW to track focus (rather
  than using FocusIn/Out events) as --use-ewmh-active-win.

- Add wid_get_attr() and use it in place of XGetWindowProperty() in
  various places.

- Remove dpy parameter from find_win() and find_toplevel() as it's unused.

- Fix a writing-to-freed-memory issue in paint_preprocess().
2012-11-04 18:45:39 +08:00
Richard Grenville e734655eef Improvement: Focus detection & --mark-ovredir-focused changes
- Change focus detection to filter FocusIn/Out events in an alternative
  way. Could break things, and may be revoked in the future.

- Change --mark-ovredir-focused's semantics. Now it determines whether a
  window is to be unconditionally focused by checking if its client
  window is the window itself. This resolves a problem in window
  managers that set frame windows to be override-redirected (Fluxbox and
  i3?). Yes, I know it's bad to change semantics in this way.
2012-11-03 22:15:51 +08:00
Richard Grenville 9fb62874c1 Bug fix: A XserverRegion leak
- Fix a XserverRegion leak introduced in b78ab316fd. I hope this is the
  reason of the slowdowns many users reported. Thanks to xrestop!

- Cache the screen region as a variable.

- Add debugging code for region allocation.
2012-11-03 10:38:29 +08:00
Richard Grenville a0b0ff5d0a Misc: Code cleanup & debug code changes
- Merge @daBrado's focus event debugging code. Thanks!

- Use macro to reduce code redundancy in various functions.

- Move focus event validation from ev_focus_out() to a separate
  function.

- Add logic in ev_handle() to increase the chance of successful window
  name detection if compton is not reading window names normally (i.e.
  if there's no --shadow-exclude), when DEBUG_EVENTS is on.
2012-11-03 05:51:40 +08:00
Richard Grenville 66d3f30978 Bug fix #17: Try to fix artifacts after animating/shading shaped wins in Openbox
- Correct design mistakes in win_get_region_noframe(). I must be
  sleepwalking when I wrote that thing!

- Intersect border_size with window region rectangle because Openbox is
  offering wrong window shapes larger than the window rectangle for shaped
  windows. Shame on you, Openbox.

- Change logic in reg_ignore calculation as border_size is now
  intersected with window rectangle and we don't need to do this here
  again.

- Rewrite window painting with frame opacity part in win_paint_win() to
  deal with absurd frame widths WM offers. Again, Openbox, this is your
  fault.

- As I'm in a pretty bad state (continuously working on compton for 10+
  hours without rest...), all these changes are not well tested, and
  bugs are to be expected.
2012-11-01 19:12:55 +08:00
Richard Grenville 46dfd1a766 Misc: Add Asciidoc man pages
Add Asciidoc man pages. The old man page is still kept, and you need to
run "make docs" to generate the new man pages and a HTML version of it.
An Asciidoc man page for compton-trans is not added yet.
2012-11-01 12:47:15 +08:00
Richard Grenville fb2ca16cb8 Improvement: border_size & ConfigureNotify & VSync changes
- Run XSync() before the final paint to catch VBlank better. Stolen from
  Xfwm4 VSync patch.

- Add --vsync-aggressive that sends out the final painting request
  earlier, simulating xfwm4 VSync patch. But this thing does have the
  possibility of breaking VSync, I think...

- Change handling of ConfigureNotify to avoid freeing w->extents and
  w->border_size if possible.

- Change logic in paint_prepreprocess() to use win_get_region() for
  border_size generation instead of border_size() if the window is not
  shaped to try to avoid some BadRegion error messages when a window
  loses its border_size then is unmapped, about which Adys complained in
  #25.

- Detect if w->border_size is None before using it in various places.
  Practically the effect is pretty limited because
  XFixesCreateRegionFromWindow() usually returns an invalid X ID instead
  of None on error.

- Fix a bug that rounded corner detection could fail if the window size
  is changed by a ConfigureNotify immediately.
2012-11-01 11:44:38 +08:00
Richard Grenville 35c9e44de2 Improvement: Try to reduce reg_ignore regenerations
- Try to reduce regenerations of reg_ignore. Highly experimental and
  could lead to very obscure bugs. More testing needed.

- Introduce to_paint in struct _win to keep track of whether this window
  was painted last time.

- Drop CAN_DO_USABLE support. Its usage looks pretty limited.

- Fix a bug that possibly causes rendering issues on frame width changes
  if frame_opacity is enabled.

- Detect other borders (instead of only top border) when determining
  frame opacity.

- Change the type of w->mode from int to an enumeration type.

- Ignore ShapeNotify if the window is not mapped, to avoid loss of
  w->border_size in some cases, which breaks the fading out process of
  shaped windows.

- Stop rendering a window if its picture is lost and it's unmapped, to
  avoid a series of X errors and possible rendering problems.
2012-10-31 10:08:48 +08:00
Richard Grenville 56e181309e Misc: Small adjustments
- Minor change of code in configure_win() for a slight performance boost
  in some cases.

- Discovered there are a lot of X errors that I basically cannot fix, caused by
  the asynchronous nature of Xlib...

- Correct the position of the timestamps in DEBUG_REPAINT. This might
  have negative effects for debugging X errors, though.
2012-10-30 18:37:49 +08:00
Richard Grenville 853d20ef56 Bug fix: Fading blocks in rare circumstances
- In very rare circumstances, poll() to the X connection returns 1 but
  no events are read out, causing XNextEvent() in the main loop to wait
  infinitely until another event comes, typically affecting fading
  process only, causing fading to appear somehow stopped. This commit
  adds a (possible) fix.

- Listen to Expose events of the X Composite overlay window if we are
  painting to it, to avoid making some parts of the screen blank when
  switching out of X screen in --paint-on-overlay mode.

- Drop "fade_fin" member of struct _win, because it's pretty useless.

- Drop unused "root" parameter of expose_root(), move get_time_ms() to
  compton.h, etc.

Richard Grenville 40178702ef Improvement: Change clear_shadow implementation
- Implement clear_shadow with painting region limitation instead of
  calculation in shadow image, to make it work correctly on windows with
  rounded corners, requested by funeral1988. This might cause more load
  on CPU, but could mean less load for GPU. The original implementation
  is kept but commented out.

- Code cleanup.

Richard Grenville f83ed19e14 Bug fix #57: Fix incorrect handling of InputOnly windows
- Stop rendering InputOnly windows. In the past I've misunderstood the
  whole thing, I guess, sorry. Thanks to garfilth and funeral1988 for
  reporting and providing valuable information.

- Fix a possible segfault in DDEBUG_EVENTS.

- Add "dbe" as a configuration file option.

- Attempt to slightly reduce the rendering delay after VSync in non-DBE
  mode. I don't think, however, that this would be greatly helpful for
  the tearing issue.
