David Turner 792bee9657 scene: Optimize rendering of single-pixel buffers 
The single-pixel buffer protocol is used to allow wayland clients to
easily draw solid-color rectangles by presenting a 1x1-pixel buffer and
scaling it to the desired size.  This patch improves how these buffers
are then handled in the scene-tree renderer.

We already ignore opaque black rectangles at the very bottom (and
anything under them) because we assume we'll be rendering on a black
background.  This patch detects black opaque single-pixel buffers and
handles them in the same way as black opaque rectangles.  It also
renders single-pixel buffers as rectangles rather than buffers because
this is probably more efficient in the underlying renderer.

In wlr_scene_surface we cache whether the attached buffer is a
single-pixel buffer.  This is done because the
wlr_single_pixel_buffer_v1 will be destroyed after texture upload, after
which it becomes much more annoying to check if the buffer is a
single-pixel buffer.
