We need to ensure that an EGL surface exists before we call
eglMakeCurrent() with it. Otherwise we might end up binding to
EGL_NO_SURFACE and then never revising that decision.
Which leads to not rendering to the backbuffer, but into the void.
Fixes X11 rendering being black
Fixes#6930
the non-shared context's surface must survive the lifetime of the
GL texture, and when the renderer gets unrealized the surface goes away,
but we cannot guarantee that all GL textures have been destroyed by
then.
So better use a context we know will survive becuase it isn't bound to a
surface.
Use the clamp() API from the previous commit to:
1. Clamp values into range
2. Emit an error if values were out of range
Unlike CSS, which just clamps and doesn't emit an error, we do want to
emit one because we care about colors being correct in our node files.
This will make it easier for themes to style radio buttons
differently from check buttons, since out CSS does not have
:has().
The concrete desire here is to use a different outline for
the focus rectangle.
Update affected tests.
Fixes: #6936
The context->variables field is expected by the resolve code to be
the keyframe variables. That code takes the style variables from
context->style anyway, so no need to pass them as context->variables
too. And crucially, the lookup code treats the keyframes variables
differently to the style variables, since it doesn't expect the
hierarchical structure that comes from parent styles. This change
fixes infinite recursion in variable lookup with css like
:root {
--a: var(--b);
}
.foo {
--b: var(--a);
color: var(--a);
}
Test included.
Fixes: #6881
We don't currently support computing transforms across native
boundaries. This could be added by using gdk_popup_get_position_x/y.
For now, just fail in this case.

The easiest things trigger the silliest mistakes. Add tests
for various properties we want our transfer functions to have,
such as:
- be inverse of each other
- stay within the defined ranges
- by symmetric around 0
Set primaries without name if supported, when named primaries are not.
But prefer named primaries if available.
This is just an attempt at defensive coding.
If we get sent primaries with the values as named primaries, treat them
like named primaries.
Fixes colorstate support on Kwin, which never sends named primaries.
If the texture covers all of the black background (like when watching a
1080p stream fullscreen on a 1080p monitor) we don't need a compositor
with single pixel support.
Fixes offloading in Kwin.
There's a ton of error checking happening that we want to do.
Because it turns out it is not really useful to create a subsurface for
the single pixel buffer when we don't even support single pixel buffers.
begin_frame_full does not return a reference, we assume that the
color state is staying alive for the duration of the frame anyway,
so end_frame simply sets priv->color_state to NULL.
