[CE] Separate framebuffer space from display space
Some devices have limited GPU capabilities and they
cannot perform client composition at the resolution
of the active display mode. For this reason the
framebuffer size can be limited with the sysrops
ro.surface_flinger.max_graphics_height|width.
As the framebuffer size can differ from the display
size, in this CL we separate the concepts for
framebuffer space and display space so we properly
render.
