Since cairos gradient code isn't flexible enough to let us
interpolate in oklch, add additional color stops and let cairo
interpolate in the ccs. This isn't as accurate as interpolating
in oklch, but it gets an ok result for fallback situations.
Make all our gradient ops adjust the hue according to
the hue interpolation.
This is currently modifying the values in the vertex array.
If reading those values back is bad, we may need to change that.
If the interpolation color state is not a default one, use the
offscreen we already for rendering big gradients, interpolate
the gradient into it, and then use a cicp convert shader to
convert the result to the ccs.
Pass the ccs, opacity, interpolation color state and hue
interpolation explicitly, and change the argument order to
match other ops.
Since we now apply opacity in the op, change the node processor
to pass colors as-is. For now, it always passes GDK_COLOR_STATE_SRGB
for ics and GSK_HUE_INTERPOLATION_SHORTER for hue interpolation.
It is nicer if gsk_gpu_color_states_create_explicit (a, a) works
regardless of whether the two are default colorstates or not.
The gradient shaders will rely on this when the ics is a non-default
color state and we use ccs == ics.
The original intent was to only realize parents recursively for
non-widget accessible objects. The implementation, however, always
try to realize parents. In the case of GtkStackPage, which is a
non-widget accessible with a widget accessible child, this breaks.
Only realize non-widget accessible parents recursively if the
current accessible is not a widget as well.

Fixes 6074a18e3e
Add a uses-gl property to our sink implementation, and use
it in the paintable code. This avoids juggling a second gl
context, with the risk of leaking it.
Calling gtk_media_stream_realize is not mandatory, but we can
still try to make dmabufs happen. Tested by removing the realize
call from GtkVideo and using GDK_DISABLE=gl.
We only need a display to negotiate dmabuf formats. Pass that
directly, instead of getting the display of the GL context as
we did so far.
With this,
GSK_RENDERER=vulkan GL_DISABLE=gl gtk4-demo --run video_player
still uses dmabufs.

This is useful for testing of repeat nodes - both performance
and conformance, and potentially even driver issues with GL_REPEAT.
We have code for manual repeating anyway, so adding a flag to force
always using it is easy.
The last part of logic in gtk_scrolled_window_measure () that accounted
for scrollbars was handling the hscrollbar first, and vscrollbar second.
For each of them, it looked at the orientation we're being measured in,
and either added or MAX'ed scrollbar's size request into ours (or not,
depending on scrollbar policy and whether overlay scrolling is used).
In case of GTK_ORIENTATION_HORIZONTAL, this resulted in
// MAX in hscrollbar width.
minimum_req = MAX (minimum_req, min_scrollbar_width + sborder.left + sborder.right);
// Add in vscrollbar width.
minimum_req += min_scrollbar_width;
whereas for GTK_ORIENTATION_VERTICAL, it was
// Add in hscrollbar height.
minimum_req += min_scrollbar_height;
// MAX in vscrollbar height.
minimum_req = MAX (minimum_req, min_scrollbar_height + sborder.top + sborder.bottom);
The former is correct and the latter is wrong: we should be adding the
size requests of the scrollbars together, and MAX'ing them with the
content size request.
Fix this by refactoring the logic to first handle the MAX'ing, and then
the addition.
This fixes the following criticals:
Gtk-CRITICAL **: 17:26:51.406: Allocation height too small. Tried to allocate 15x31, but GtkScrollbar 0x2a00fac0 needs at least 15x46.
that were happening when all of:
- scrollbar policy was set to ALWAYS,
- overlay scrolling was disabled,
- the scrollable child was really small.
