Squashed commit of the following:
apps/examples/pwfb: Fixes compile and early debug issues.
apps/examples/pwfb: Code complete!
apps/examples/pwfb: Flesh out the motion logic.
apps/examples/pwfb: Add an example/test case that will, eventually be used verify the per-window framebuffer logic. This is not even code complete at this point.
