Squashed commit of the following:
Update TODO list
graphics/nxbe: The moverectangle renderer now supports updates to the per-window framebuffer (unclipped) as well as the graphics device memory (clipped).
graphics/nxbe: The filltrapezond renderer now supports updates to the per-window framebuffer (unclipped) as well as the graphics device memory (clipped).
graphics/nxbe: The getrectangle method now returns data from the per-window framebuffer if available.
graphics/nxbe: The fillrectangle renderer now supports updates to the per-window framebuffer (unclipped) as well as the graphics device memory (clipped).
graphics/nxmu: If a window supports a per-window framebuffer, then redraw callbacks are suppressed and the device content is updated from the shadow, per-window framebuffer. graphics/nxbe: The copyrectangle renderer now supports updates to the per-window framebuffer (unclipped) as well as the graphics device memory (clipped).
graphics/nxbe/nxbe_setsize.c: Reallocate the per-window framebuffer when the window size changes.
