lcd-16bit-common optimize bitmap_part

Browse source 
in testing this slightly speeds up any of the draw routines using fg or bg
and slightly slows down the ones that don't
being that these are already faster it serves to bring them closer in
ops per second

.. and slightly speeds up the most general case DRMODE_SOLID
