Even when we have tons of width available, still do the wrapping at
max-width-chars.
This is what happened in GTK3, too, but it happened automatically
because GTK3 did for_size = MIN (for_size, nat_size) and GTK4 does not.
So we do this manually in the label now.
Fixes the label-sizing.ui reftest.
Make it use gdk_memory_texture_from_texture().
Also make gdk_memory_format_alpha() privately available so that we can
detect if an image contains an alpha channel.
Don't pass texture + rect, but instead have
gdk_memory_texture_new_subtexture()
and use it to generate subtextures and pass them.
This has the advantage of downloading the a too large texture only once
instead of N times.
Close widget-factory and observe:
Thread 1:
* acquire main loop
* handle close button
* close window
* dispose video and media stream
* stop GstPlayer
WAIT on pipeline stopping
Thread 2:
* prepare next image in pipeline
* hand image to GtkGstSink
* create GdkTexture from image
* gdk_gl_texture_new() determines format
WAIT on acquiring main loop
Sounds like a deadlock?
Indeed, so don't do that.
It does not belong in GdkGLContext, it's a renderer thing.
It's also the only user of that API.
Introduce gdk_gl_context_check_version() private API to make version
checks simpler.
It turns out glReadPixels() cannot convert pixels and you are only
allowed to pass a single value into the function arguments. You need to
know which ones or things will explode.
GL is great.
... if the current locale has a different starting day than Sunday.
This needed 2 fixes:
* We need to take into account `calendar->week_start` when
creating/adding the appropriate `day_name_labels` field
* we were only calculating `calendar->week_start` _after_ attaching the
`day_name_labels`, so it was still set to 0 (the default value).

Pass a format do GdkTextureClass::download(). That way we can download
data in any format.
Also replace gdk_texture_download_texture() with
gdk_memory_texture_from_texture() which again takes a format.
The old functionality is still there for code that wants it: Just pass
gdk_texture_get_format (texture) as the format argument.
Otherwise if we hide and show a window we recreate a new surface,
breaking the compositor's association, but potentially not resend this
data for the new surface.
This matches what we do for input_region.
This is supposed to test the most fallback GL stuff, so we might want to
set even more env vars here.
Also enable the run for the Fedora builder in CI.
