leftovers:
1) config file path. Has to implement compatibility functionalities before
we can change it.
2) links in man pages. Has to migrate the repo first.
3) _COMPTON_SHADOW, it has become a defacto standard, so we have to keep
supporting it.
4) dbus names, undecided whether we should/could change it.

Because first frame no window has their pixmap bound, which doesn't
happen in frames after the first. If a window is unmapped in that frame,
the compositor will try to render a window with no pixmap bound if
fading is enabled.
Now we keep track if we are in the first frame, and if that's the case
we skip fading in unmap/destroy.
Fixes#239, bug number 2

xerror handler might be called during XCloseDisplay, at which point
session_t is already destroyed, causing a segfault.

When enabled, the result will be redirected to a window, and compton
won't take over the screen.

To prepare for different blur methods, the blur interface of backends
has been splitted into two parts.
Now to use blur, a blur context must be created first; then, the blur
method should be called with the blur context created.
Updated the existing backends to the new interface. Also implemented
handling of the new blur options.

Delay focus updates until critical section. Rational is that focus
events might arrive when the focused window hasn't been managed by
compton, result in that that window not being focused.
This commit makes compton mark focus update events, and only update
focus in critical section, after we managed all the new windows.
Fixes#177

Remove more unused stuff.
Also removed session::xinerama_scrs, since all the information we need
is covered by xinerama_scr_regs. Convert uses of xinerama_scrs to use
xinerama_scr_regs.

Currently compton handles window creation event by immediately query all
the information it needs and create a window struct with that
information. However, this is prone to race conditions.
In the future, we want to react to window creation event by creating a
placeholder in the window stack, and only query window information in a
critical section where the X server is grabbed by us.
This commit split struct win into two struct, one as placeholder, the
other for holding actual window information.

Use a flag to mark whether the image needs update, and only update once
per frame.
Also refactor some common code into functions, and handle image errors
properly.

Choose the best vsync method for the user, instead of asking them to
frustratingly try every one of the options to see what works.
With this commit, the `vsync` option will take only a boolean value.

Rational: current workaround for Composite < 0.2 doesn't work with the
GLX backend, it also doesn't handle window border properly. Plus,
Composite 0.2 came out more than a decade ago, it's safe to assume
everyone has it.

Instead of storing them as an array of xfixed.
Might cause some performance overhead for the new backend, because
it is allocating a buffer to do the conversion every frame. Will fix
later.

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.

Handle SIGINT using libev's ev_signal handler, instead of using
sigaction().
Fixes#64. But compton might miss signals when it's not in the main loop
(e.g. when compton is reset), and thus not exit "clearly". It should
cause any real problem though, so we don't care.

Put them all into one function, and move the function pointers out of
glx_session_t, making them global variables (because them don't change
after initialized). Remove the function pointer typedefs and replace
them with the ones in glxext.h
We also only lookup the functions once per a lifetime of compton.

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.
Also, some code sharing between the old and new glx backend.

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.
