Create a GL context handler subclass of recently added context handler base class and
rework code to use it. This simplifies a lot of things, like: switching of importers
at runtime, handling context queries, sharing data between importers, etc.
In order to bridge work with GL between GTK and GStreamer reliably, we need to create and
check context capabilities ahead of time. We also need to be able to query context at any
time during playback. Also we should avoid changing importers on context queries, this can
lead to all sort of problems.
To be able to achieve all of above, introduce new context handler base class that works
separately of importers.
When we prefer GLES, make sure its no lower then 3.1 version, so it can color convert 10bit videos,
otherwise core GL 3.2 that GTK4 normally defaults to takes precedence.
With auto behavior we should select the best one, both performance and support wise.
Otherwise user can request one or another with GST_GL_API env that works best
with his specific HW.
Unlike legacy sink that used GLArea, GdkPaintable snapshots without pre-multiplying
sizes with scale factor. Remove scaling multiply of our widget dimensions,
so both video and widget width/height will be calculated correctly.
This fixes both image and black borders displaying issues on displays with
non-100% scaling applied.
GStreamer does not take pixel aspect ratio into account for overlay rectangles.
If we do so, we end up with subtitles that are displayed off-center.
Behave like any other GStreamer sink on this matter.
Instead figuring out what kind of pool we should make just use the upstream provided
functionality that comes as part of GLUpload API.
Fixes uploads with GstVideoGLTextureUploadMeta, which legacy VAAPI plugin uses on GLX.
This tries to avoid "scrambled" image on Linux with Intel GPUs that are mostly used
together with x86 CPUs at the expense of using slightly slower non-direct DMABuf import,
by not going with GLES by default on EGL.
The "GST_GL_API" env can still be used to force one or another context type.
We need for GStreamer to be aware of currently used DRM modifier first. On the other
hand forcing GL everywhere would break most embedded systems that only work with GLES,
so do it for x86 processors only... and pray for it to work.

We no longer ship the web app that was reusing parts of this code.
Combine it into single file without additional subclass.
Also put window creation inside first activate code instead of startup
in order to fix running app as a gapplication service.
There were various problems with importer loader code. One defect was that
it kept managing a single global list of available importers and marking
which one is currently used on it. This made it not work correctly for
multiple sink instances in single process and was not thread safe.
This commit changes importer loader code into a GstObject subclass, which
keeps its own list of importers per instance and unlike before makes it
possible to free this data from memory when destroyed.
Now only open modules are kept always in memory until process finishes
since we cannot unload them once loaded anyway.
With updated CSS we use some variables intoduced in stable versions of libadwaita. To make it work properly, stop using alpha.2 and build recent stable version.
Fixes for recent libadwaita provided theme, mainly needed to workaround:

Devs rejected my idea of fixing it upstream. They said to override it
in my own app. So here it is.
A resume video question dialog that keeps poping confuses new Clapper users.
Looks like some spam. Change default option value to be disabled, so people
that are interested in this feature can enable it in preferences.
We do not support zero width/height (described in our caps). Set initial video
dimensions to 1x1. They are going to be updated on first buffer after video info is set.
This avoids running into https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1139
and makes sure we do not do any divisions by zero here either.
