`thread_current_context` might be holding the last reference to
`previous`, in which case `gdk_gl_context_make_current` on the new
context will free `previous`, leaving it a dangling pointer.
Avoid this by making sure to hold a reference.

Opaque textures don't clamp to transparent but instead to black.
We didn't consider this, so we were blurring their edges into blackness
not into transparency.
Fix this by adding the GSK_GPU_AS_IMAGE_SAMPLED_OUT_OF_BOUNDS flag
and respecting it in the implementation that uses it.
Test included.
Fixes#6980
Swizzling is not respected for blitting.
See commit 058252e895 for the same change in Vulkan.
Apparently that never made it to ngl.
The next commit will have a test for this.
I've had a need for flags for the get_as_image() call but so far have
been able to work around it. But now it seems I might finally need it.
This just introduces the flags but doesn't add any.

Set the alpha channel to "undefined" in this case.
Gimp doesn't seem to like this when opening the image and insists to
doing something with it, that's a bit of a bummer.
But it allows GTK to load RGBx textures.
This variant takes the color_states, instead of computing it
anew from the ccs and the color state of the color. This will
be used to pull this work out of the loop in add_glyph_node.
It seems Mesa doesn't support that yet, but having it doesn't hurt.
And it allows drivers to allocate less memory for the swapchains,
because we don't need all the 4 images we request in minImageCount.
But drivers tend to take that minimum image count as gospel, so we need
to use a higher number to not cause lag in corner cases.
Removed via regex and grep.
The following were intentionally not removed:
- GtkImage:file: (attributes org.gtk.Property.set=gtk_image_set_from_file)
- GtkImage:resource: (attributes org.gtk.Property.set=gtk_image_set_from_resource)
As they have no getter and (setter PROP) without a (getter PROP) crash
gobject-introspection. This is fixed by
ad3118eb51.
The annotations should only be set when the name of the setter or getter
for a property "GtkClassName:prop-name" is not gtk_class_name_g(s)et_property_name.
