Don't call map_win() in add_win()
Only case where you want to map window in add_win() is during compton
startup, when compton is registering existing windows. Otherwise,
add_win() is always called for newly created windows, so there will
always be a MapNotify coming up for that window. If we map newly created
windows in add_win(), we will try to map it a second time when the MapNotify
arrives.

So, just don't call map_win() from add_win(). For compton startup, we
explicitly call map_win() after calling add_win() in session_init.

Don't start fading when screen is unredirected
If a window is destroyed and starts to fade out when screen is
unredirected, when the screen become redirected again, we will generate
errors when trying to render that window.

Also make sure the assumption that all window are either MAPPED or
UNMAPPED when screen is unredirected holds.

Fix a use-after-free
paint_preprocess takes head of the window list as an argument. The
actual head of the window list might be freed and deleted during processing
of fade, but paint_preprocess will keep using the old head of the list,
thus uses freed memory.

Solution is just don't pass the head as an argument. paint_preprocess
will use session_t::list directly.

Cut fading short if we decide to unredirect the screen
Previously if we unredirect the screen while a fading is in progress, we
will "resume" the fading when we redirect the screen again.

This is usually fine unless the window being faded out is destroyed. we
still tries to fade it out, but since we don't have the pixmap of the
window anymore (freed by unredirect), we will generate lots of errors
until the window is completely "faded out".

Also this change makes it easy to reason about things. Now we know when
the screen is unredirected, all the windows can either be in MAPPED or
UNMAPPED state, nothing else.

Destroy Input Only window properly
Destruction of Input Only windows is erroneously ignored by commit
cea010a, causing future window with the same window id as the destroyed

Remove win::*_last
A side effect of this is that some window properties are allowed to
change during fade-in/out. (e.g. window background can become blurred
during window fade out if window properties changed so blur is requirired).
But it is unclear what is the expected behaviour in this case anyway, so we
choose the one that is simpler to implement.

Window state tracking refactor
Window state tracking is basically the back bond of window fading. We
add a new enum field to the win struct to track the state of the window,
instead of using a set of boolean variables. We also remove the fading
callbacks, since it is only used for fading, so the potential of code
reuse is lost. And it makes the code slightly harder to understand.

Also fixed a problem that --no-fading-openclose is not behaving as
advertised (from my observation, enabling this flag disables fading
entirely, instead of just diabling it for open/close).

Also uses double for opacity everywhere internally. Use opacity_t only
when setting X opacity prop.

Refactor FBConfig lookup
Background: To bind a Xorg window content to a OpenGL FBConfig, which
has to match the color format the Xorg window is using.

Previously, compton just find a FBConfig that has the same depth. This
led to chjj/compton#477, which has been fixed by a ugly hack.

The commit refactor the lookup mechanism to take as much into
consideration as we reasonably can. Hopefully preventing similar
breakages in the future.

Parse number locale-independently
Previously we were using glibc's strtod function to parse floating point
numbers. The problem is, strtod is locale dependent. Meaning 7,7 might
be parsed as two numbers (7 and 7) in one locale, and parsed as one
number (7 point 7) in another locale. This is undesirable.

We need to set the locale to a value we know to make number parsing
consistently. We could use setlocale(), but that is not thread-safe. We
can also use uselocale(), which is thread-safe, but doesn't cover strtod
(Yeah, some of the locale-aware functions only acknowledge the global
locale, not the thread local one).

So in frustration, I just wrote a simple floating point number parser
myself. This parser obviously doesn't cover all cases strtod covers, but
is good enough for our needs.

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.

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

Also, the kernel size calculation doesn't really make sense to me.

distribution. As far as I can tell, there is no perceivable difference.
Except now the effective shadow radius is smaller for the same config.

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:
