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 45a260b433 Print warning messages for multipass blur
Multipass blur is not properly implemented for xrender backend. There is
visible artifacts when it is used. And it is quite difficult to
implement correctly and efficiently for the xrender backend.

Print a warning message for multipass blur so we can survey whether it
is actually been used.

No functionality is removed in this commit.

and you want to have shadows in those areas.

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.

Yuxuan Shui 309a4cec79 Make monitor_repaint an option
This is a potentially useful feature for debugging the xrender backend,
so make it a commandline option rather than an obscure compiler flag.

Also this is only usable with xrender, for glx there are better tools
for debugging.
