Disable timing estimation based pacing by default, as it might not work
well across drivers, and might have subtle bugs.
You can try setting `PICOM_DEBUG=smart_frame_pacing` if you want to try
it out.

Factored out vblank event generation, add abstraction over how vblank
events are generated. The goal is so we can request vblank events in
different ways based on the driver we are running on.
Tried to simplify the frame scheduling logic, we will see if I succeeded
or not.
Also, the logic to exclude vblank events for vblank interval estimation
when the screen off is dropped. It's too hard to get right, we need to
find something robust.

This is where we keep temporary, short living, private debug options.
Adding and removing command line and config file options are
troublesome, and we don't want people adding these to their config
files.

Present extension based scheduler doesn't work well on NVIDIA drivers.
GLX_SGI_video_sync is less accurate, but is rumoured to work. See
[kwin's usage](https://invent.kde.org/plasma/kwin/-/blob/master/src/
backends/x11/standalone/x11_standalone_sgivideosyncvsyncmonitor.cpp)

This option accepts a list of patterns and overrides the corner radii of

there are two x extensions for working with monitors (especially
multiple): xinerama and randr. xinerama is old, feature-poor and in
general isn't used anymore compared to the randr: new, feature-rich and
widely-used. for some reason we were using both of them, so let's drop
xinerama to keep things simple, clean and small. and to be modern.
the drop was done in three steps:
* first step was to replace all the xinerama-based code with the
randr-based one and to replace or remove all the xinerama mentions;
* second step was to replace the xinerama's terminology with the
randr's one. xinerama was referring only to the word "screen", while
randr refers to multiple words and i think the word "monitor" is the
most suitable for us and, hopefully, clear both to a contributor and
to an end user;
* third step was to refactor the new randr-based code if needed and to
address related todo's (mostly about moving related functions
elsewhere).
all the steps were done well except addressing a leftover todo about
moving the win_update_monitor function to the x.c which wasn't done.
the xinerama-shadow-crop option was renamed to crop-shadow-to-monitor,
but it's previous name is still accepted, has effect and the
deprecation message is printed to preserve backwards-compatibility.
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.
