[Crystal-cvs] CS/plugins/engine/3d light.cpp,1.9,1.10

[<jo...@us...>]

Update of /cvsroot/crystal/CS/plugins/engine/3d
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv1510/plugins/engine/3d

Modified Files:
	light.cpp 
Log Message:
	- Jorrit did a huge optimization and cleanup on dynamic lights (old
	  style dynamic lights which do NOT use stencil hardware). Pressing
	  'L' in walktest (which adds a huge dynamic light at the current
	  spot) improved from 22 seconds to something slightly bigger then
	  0 seconds (for a big level). To do this I had to remove support
	  for shadows. I don't think shadows for dynamic lights are that
	  important. They will still correctly shadow if they shine through
	  a portal (i.e. the portal boundary).
