[Scummvm-cvs-logs] CVS: scummvm/common scaler.cpp,1.12,1.13

[Max Horn]

Update of /cvsroot/scummvm/scummvm/common
In directory sc8-pr-cvs1:/tmp/cvs-serv30360

Modified Files:
	scaler.cpp 
Log Message:
fix advmame scaler ('flickering', observable in e.g. Sam&Max, and the left-screen-border-black bug). Note: this change might look fishy to you but is perfectly legal because our frame buffers put a border around the screen data to accomodate for this
