A little more progress toward the implementation of per-window framebuffers. Still missing:
...
- Logic that generates the low lever framebuffer renderers for the per-window framebuffers,
- The logic that picks off the per-window framebuffer updates from normal graphics device updates. This logic must update both the per-window framebuffer and the graphics device (from the framebuffer).
Squashed commit of the following:
graphics: Add logic to allocate the per-window framebuffer.
graphics: A few fragmentary thoughts on how a per-window framebuffer could be represented and allocated.
