+  Title:       PER-WINDOW FRAMEBUFFERS
+  Description: One of the most awkard things to handle in the NX windowing
+               system is the re-draw callback.  This is difficult because it
+               requires ad hoc, custom logic to be able to do the redrawing
+               in most cases.
+
+               One solution would be to provide a per-window framebuffer.
+               All rending would be performed into the per-window framebuffer
+               and the rended bits would be copied the LCD or framebuffer
+               device memory on demand when the redraw is required.
+
+               This would (a) greatly simplify the graphics interface, (b)
+               greatly improve redraw performance, and (c) enable a more
+               generic use of the windowing.  The downside would be a large
+               usage of memory to hold all of the framebuffers, one for each
+               window.
+  Status:      Open
+  Priority:    Low, of mostly strategic value.
