A clip should represent the area that is covering the current FB associated
with the CRTC. So making sure each input rect covers any area in the FB is
the first thing to do. If that is the case, the size and coordinates should
be adjusted based on the partial area in the FB the each rect covers. The size
elements need to be truncated if the rect's size exceeds FB's for the CRTC.
Then offsets should be applied to coordinates if the CRTC's offsets aren't 0.
And coordinate transposing and inversion are needed in case the rotated image
is assigned to the FB.
