linux-rasp-pi: Remove custom cursor code

Browse Source 
This code was added as an optimization for showing a mouse cursor on
the Raspberry Pi.  What happens though is while the mouse cursor does
move more smoothly, the actual application becomes less smooth when the
mouse cursor is moved.  By removing the custom cursor code, performance
will no longer be effected by rendering a moving mouse cursor.
