Move rendering related functions out of compton.c
Moved:
* Blur kernel related functions to kernel.c
* Vsync related functions to vsync.c
* paint related functions to render.c

This will make the `split-backend` branch easier to rebase.

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.

Make sure the vsync methods are really available
libglvnd seems to return a pointer to a function that does NOTHING
for things the backing driver doesn't support.

So we check if the extension is actually advertised before using it.

Clean up the wintype option logic
I just realized wintype option shadow and fade never worked. If you set
the global shadow option to true, wintype shadow option will have no effect.

Now the wintype options will properly override the global ones.

Also remove deprecated options from compton.sample.conf.

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.

Yuxuan Shui b18d46bcbd Revert "Remove xrender-sync and xrender-sync-fence"
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.

This is a potentially useful feature for debugging the xrender backend,
so make it a commandline option rather than an obscure compiler flag.
