[Torbj?rn Andersson]

Update of /cvsroot/scummvm/scummvm/sword2
In directory sc8-pr-cvs1:/tmp/cvs-serv17578

Modified Files:
	controls.cpp function.cpp sword2.cpp 
Log Message:
Adapted LavosSpawn's idea for more efficient screen updating. It still
renders the entire screen every frame, but it tries to update (i.e. copy to
the backend) only the parts of the screen that actually changed. At least
approximately so.
