Transparent clipping interacts poorly with programs whose transparent
interface elements must show windows below them for functionality,
for example screenshot utilities.
This needs the EGL_KHR_image_pixmap and the GL_EXT_EGL_image_storage
extensions, which unfortunately aren't available on NVIDIA cards.
Don't add documentation for these, for now.

Used for setting custom window shaders and rules for choosing custom
window shaders.
Added a "c2_userdata_free" parameter to c2_list_free, so allocated userdata
stored in nodes can be freed.

It was deprecated in v6, but wasn't formally deprecated back then (e.g.
no warnings were printed for it). So formally deprecate it here.
This also left the refresh-rate option unused, so that will be
deprecated too.

Added the new `clip-shadow-above` configuration and wintype option.
These allow the user to select windows to clip from the shadow region of
other windows, i.e. don't paint shadows on top of them.
This should provide a more useful and userfriendly alternative to the
deprecated `shadow-exclude-reg` option — especially for docks and bars.
**Work-in-Progress**
Add `dual_kawase` to configuration and argument parsing. Allow `kawase`
for backward compatibility. Add `--blur-strength` parameter for
blur-method `dual_kawase`.
Update documentation to reflect the new blur-method and parameters.
Transparent windows usually blends on top of other windows, this commit
adds an option to make transparent windows clip other windows like
non-transparent windows do.
Closes#265

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.

A quick search on GitHub showing the _COMPTON_SHADOW is actively being
used (most noteably, by polybar). It is not a difficult thing to support,
and it doesn't have that much runtime overhead. So remove the option
that guards this feature, make it enabled by default.
(Side note, I saw lots of people putting this option in their config
files, but this is actually a command line only option.)

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

Setting glx-swap-method to value other than "undefined" and "buffer-age"
could potentially cause rendering problems. So remove them, the meaning
of the remaining options can be more precisely captured by "use-damage",
so create a new option under that name.
--glx-swap-method is deprecated in favor of the new option --use-damage.

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.

* Make some functions in win.c pure
* Remove unused code
* Fix misuse of attr_const, const functions shouldn't exam data pointed

Now both the old and the new backends are compiled in, the user can
choose which one to use with a command line switch.
Lower the barrier for testing.

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.

If fork is requested, we fork as early as possible, way before anything
is initialized. This way, we don't need to do the gymnastics to make
OpenGL work properly across fork.

Slightly clean up header inclusion with the help of clang's module system.
It's better for files to include the things you need directly.

Move filling winopts with default values to after command line options have
been parsed, not after parsing the config file. This is more intuitive.
