[Scummvm-cvs-logs] CVS: scummvm/sword2 build_display.h,1.17,1.18

[Torbjörn Andersson]

Update of /cvsroot/scummvm/scummvm/sword2
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv2543

Modified Files:
	build_display.h 
Log Message:
Replaced drawLine() with a shorter version described in Wikipedia. It uses 
a callback to plot each point so that it doesn't need to worry about how
the caller deals with screen dirtying, etc.

My plan is to move this function into a standard class. (That's why I used
the American spelling "color" instead of "colour".) I just haven't made up
my mind on which is the most appropriate one yet.
