Make buffer age not glx specific

Make buffer age not glx specific
Buffer age is not a glx specific concept. xrender backend can have
buffer age too, if double buffering is used (required if we want to use
Present). So, make buffer age a generic concept in compton is required
for further backend improvements.

Moved buffer age based damage aggragation out of glx as well.

Make sure draw_idle is stopped in all cases
Previously, compton fails to stop draw_idle in some cases when sw_opti
is enabled.

sw_opti is a feature that limits the draw frequence to vblank frequence.
It adds a delay to drawing when the screen is updated more frequently
than the vblank frequence. However when the delay is not used (i.e. the
screen is updated infrequent enough), compton will start drawing the
frame directly without using the delay. And specically in this case,
compton will fail to stop the draw_idle, causing a callback to be called
once per loop of the mainloop, resulting in high CPU usage.

Fixes #92

Enable the glStringMarker logger when available
glStringMarker is usually only available when running under some
kind of GL debugger, and can be used to insert strings into the
GL command string. Writing logs using it can be useful, since it
lets us correspond GL calls with what happens in compton.

More info about the extension can be found here:

First step of split backend into modules
This commit introduced a new, modular backend interface. The interface
is not very good, since I don't think I fully understand all the
requirements writing a backend have. But this is a good first step.

This commit also includes an initial xrender backend written using the
new interface, and some opengl backend related helper functions, which
are taken from the old opengl backend.

However, there is not integration with the core compton yet. compton
will still use the old backend code. This commit is here so we can get
the automated build test.

What is implemented in the new xrender backend:

* Windows with transparency
* Shadow
* Opacity
* Wallpaper (getting the root pixmap)
* Blur

Known problem with the xrender backend:

* It is slower

Things that still need to be figured out:

* What is the better way to add vsync to the new backends

Make the shadow actually gaussian
The old shadow kernel formula is not "wrong" per se, as the only judge
is if it looks good. However, the formula used is not really gaussian.
Also, the kernel size calculation doesn't really make sense to me.

This commit change the kernel formula to actually use a gaussian
distribution. As far as I can tell, there is no perceivable difference.
Except now the effective shadow radius is smaller for the same config.

Also, made that part of code a bit more mordern.

Yuxuan Shui bcab5d1518 Workaround the incompatibility between DRI2 and xcb
When using DRI2, Mesa uses XESetWireToEvent to hook into Xlib's event
handling loop, so it can get notified when certain DRI2 event happens,
which is crucial to the normal functioning of GLX.

When xcb is owning the event queue (meaning libxcb is doing all the
event handling), those functions registered by Mesa will never be
called, thus GLX will malfunction, leading to screen flickers or visual
artifacts.

This commit uses a hack from Qt to manually call those functions in
compton.

This reverts commit 50e2259404.

Temporarily revert the removal until we have more information about this whole
thing.

Turns out a couple of drivers don't work properly without the sync fence,
including intel, llvmpipe and NVIDIA.

Although sync fence is needed, from the information I have gathered (looking
at old bug reports, protocol specifications, look at other compositors' code),
compton's usage of it is not proper. So we need to rewrite it in the future,
after we get more information from driver developers.

Yuxuan Shui 50e2259404 Remove xrender-sync and xrender-sync-fence
This was a dubious "fix" for a Nvidia driver problem. The problem was
never fully understood, and the then developers took a shotgun approach
and implemented xsync fences as a fix. Which somehow fixed the problem.
Again, I don't see any indication that the developers understood why
this "fix" worked.

(for details, see chjj/compton#152 and chjj/compton#181)

The driver problem should have been fixed almost 5 years ago. So this
shouldn't be needed anymore. In addition the way compton uses xsync fences
is apparently wrong according to the xsync spec (fences are attached to
screen, but compton uses them as if they were attached to drawables).

So, I will try removing it and see if anyone will complain. If there are
real concrete reasons why fences are needed, it will be brought back.

Uli Schlachter 9bb3327549 Die when the X11 connection breaks
With libX11, the library calls an I/O error handler if the connection to
the server breaks. The default I/O error handler prints an error message
and calls exit(). This can be seen when running a "pre-xcb" compton
against Xephyr and then closing the Xephyr window:

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":1"
      after 241 requests (241 known processed) with 0 events remaining.

The current compton would just continue running. After this commit, it
instead exits with this message:

Yuxuan Shui 2a4fed50f4 Use libev for inputs and timeouts
Bugs:

* There seems to be a noticeable frame loss when window
  is being opened/closed. But the same problem also exists
  in master/next, so this is not a regression.
* Using --sw-opti and --benchmark at the same time causing
  compton to draw more frequently than permitted by the
  arguments. That is because the sleep interval calculation
  is flawed. Not really a regression either.

Verified still working:

* Usual painting
* Fade
* Benchmark mode
* --sw-opti (with or without benchmark mode)
* DBus
* Unredir delay

Yuxuan Shui 28a2cc62fa Convert XfixesRegion to pixman region
Re-did the painting logic, and document it.

It is unclear to me what is the previous painting logic. But the current
one is basically this:

1. Go through all windows top to bottom, and put visible windows (not
   unmapped, opacity > 0, etc) into a linked list, from bottom to top
2. Accumulate a region of ignore on each window, which is basically the
   region of screen that is obscured by all the windows above current
   one.
3. Paint all the visible windows from bottom to top. Subtract the region
   of ignore from the painting region. If we need to paint shadow, we
   subtract the body of the window from the shadow painting region too,
   because we don't want shadow behind the window.
4. region of ignore is invalidated when window stack change, an
   window on top moved or changed shape, when window changed between
   opaque and transparent, etc.

Notes:

It is unclear whether all the different shapes of a window (extents,
noframe, border, bounding shape, etc) are calculated correctly or not.

It is unclear if window shape related events are handled correctly or
not. Need more testing.

Yuxuan Shui 7af815a0aa Proper fix for screen freeze
If an X event is received at a very specific point in time, it can trigger
a race condition in Xlib. Said event will be read, but Xlib will
nonetheless be completely unaware of the event.

This cause compton to sometimes block on select() while there are events
ready to be processed. If the event is a damage report, screen freeze
will happen until some other event is received.

The proper fix is to switch to xcb for event handling, thus avoid this
problem entirely.

Yuxuan Shui 967d9f32ea Workaround for what seems to be a race in Xserver
There seems to be a race between DamageAdd (what the client uses

sure how to confirm this. But this (terrible) workaround seems to
solve this problem.

Before becoming the selection owner for _NET_WM_CM_Sn, compton will now check if
that selection is already owned (which means that another composite manager is
already running). If this check fails, startup will be refused. This behaviour
is required by EWMH / ICCCM.

Because this should catch all composite managers, the error message that was
used before when another manager is already running is reworded to mention that
the other manager does not follow EWMH.

Yuxuan Shui cfdb946992 Avoid using window id as identifier in finish_destroy_win
Under extreme race conditions (window A close at the same time as window
B create), there can be multiple windows with same id in compton's window
list. If at this point window B closes itself as well, finish_destroy_win
might destroy a different window as what's passed to destroy_callback.

This can be a problem because someone can still hold a reference to that
window (e.g. 't' in paint_preprocess), and there's no way to clear that
reference. If finish_destroy_win always destroy the same window passed
to destroy_callback, this will not be a problem.

Bug fix: Select the larger of the X window border width and
_NET_FRAME_EXTENTS, instead of adding them together, when determining
the frame extents. (Supposedly) more EWMH compliant, as EWMH
_NET_FRAME_EXTENTS should include the X window border width already. We
did not choose to completely rely on _NET_FRAME_EXTENTS to remove the
need to keep track of whether there is a _NET_FRAME_EXTENTS, and
(hopefully) take care of some cases when it is wrong. The commit should
fix awesomeWM/awesome#425. Thanks to psychon for the information. (#302)

The commit fixes the bug in win_get_region_noframe() that the X window
border width is not considered when determining the width/height of the
window without frame, as well.

  backend. --xrender-sync-fence requires a sufficiently new xorg-server
  and libXext. NO_XSYNC=1 may be used to disable it at compile time.
  Thanks to tchebb for reporting and everybody else for testing. (#181)

- A bit code clean-up. Replace a few XSync() with XFlush() to minimize
  the latency.

Richard Grenville fbd70e146c Feature: Add XRender-GLX hybird backend
- Add new backend "xr_glx_hybird", which uses X Render for all
  compositing but GLX on the last step of rendering to screen.  This
  makes GLX-backend-specific VSync methods usable while may avoid
  certain bugs with GLX backend. The idea comes from ali1234.
  Experimental.

- GLX backend: Stop using or rendering to depth buffer.

- Use glFinish() instead of glFlush() before VSync. It probably uses
  more CPU but could be more reliable than glFlush().

  etc.) and through win_get, primarily for debugging.

- Add helper macros likely(), unlikely(), cmalloc(), ccalloc(),
  crealloc().

- Change w->opacity_set to opacity_t. Determine display_repr in
  session_init(), etc.

Richard Grenville d8977408fd Bug fix #153: Possible fix for a rare timing issue
Possible fix for a very rare timing issue in focus detection. Compton
may fail to detect the currently focused window, when a window newly
mapped gets focused, we failed to listen to events and get FocusIn from
it in time, and a series of focus change events before it happens stay
in the event queue and puzzled compton. My choice is to force focus
recheck on all focus-related events. More roundtrips to X, but not
necessarily worse performance, due to the high cost of focus flipping
especially when there's a lot of conditions. Thanks to SlackBox for
reporting.  (#153)
