ZVISION: Set all the internal graphics operations to use RGB555 (1/2)

This is the first part of the changes to make the engine use RGB555
internally again. This is done to simplify the rendering pipeline -
the engine will use RGB555 internally, but will output to RGB565.
The overall changes have been broken into two commits, thus this
first commit will break all the game colors
