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.
Broadway is the only GTK+ backend that throws an error on stderr for a
"display server" connection failure.
This causes problems when gtk_init_check() is used and unexpected error
output is generated such as with hotdoc, which fails when generating a
GTK plugin's documentation instead of overlooking the issue.
"Unable to init server: Could not connect: Connection refused"
Broadway is the only GTK+ backend that throws an error on stderr when
failing to initialise, which causes problems when gtk_init_check() is
used and unexpected error output is generated.
This causes hotdoc to fail when generating a GTK plugin's documentation
instead of failing quietly.
"Unable to init server: Could not connect: Connection refused"
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.
Add gdk_gl_context_is_api_allowed() for backends and make them use it.
Finally, have them return the final API as the return value (or 0 on
error).
And then use that api instead of a use_es boolean flag.

The only type we have with this prefix is the
deprecated duplicate of gsk_gl_renderer_get_type(),
and including it causes some tests to break.
So skip it.

menu models could use markup for items and the markup would
be parsed, but this was not intended behavior.
This commit adds official support for using markup
for menu items via the `use-markup` property.

Make a deep texture, if the render nodes have
high depth content.
For now, we use 32F here for the deep format,
since using 16F causes small rounding errors
that break the memorytexture roundtrip tests.
Look at the framebuffer and the rendernode to
determine what format to use for intermediate
textures.
Our preference here is to use fp16, if we have it
and it makes sense for the framebuffer we're given.
Add private api to find out if the content
of a render node should be considered 'deep'.
The information is collected at creation time,
so there is no tree-walking involved when we
are using this information in the renderer.
Currently, this comes down to whether there are
any texture nodes with high depth textures in the subtree.
In the future, we may want to allow marking gradient
nodes in this way as well.
For MemoryTexture, this is a simple change.
For GLTexture, we need to query the format at texture creation. This
sounds like a bad idea and extra work until one realizes that we'd
need to do that anyway when using the texure the first time - either
when downloading, or when trying to use it in a rendernode, where we
will soon need that information to determine if the texture prefers high
depth.
