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.

Change `win *` to `win **`, because a window could be freed by the

Uli Schlachter aa8cb217c8 Fix xcb error ignoring
The existing mechanism with set_ignore_next() is (IMHO) ugly and also
does not work with XCB requests. This commit adds a new function
set_ignore_cookie() and fixes callers that were converted to XCB to use
this new function instead.

Uli Schlachter 00ae9718ee Handle asyncronous X11 errors
Errors for requests sent via Xlib that expect a reply are handled via
XSetErrorHandler(), which sets up a callback function that Xlib calls.
Errors for requests that do not expect a reply or for errors caused via
unchecked XCB requests show up as events of type 0 in the event handling
function.

Before this commit, errors were ignored here. This commit changes the
code so that the errors are printed instead.

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.
