SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Update of /cvsroot/bprocessor/gl/src/net/sourceforge/bprocessor/gl/view
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv19988/src/net/sourceforge/bprocessor/gl/view

Modified Files:
	AbstractView.java View.java 
Log Message:
Improved hit detection of vertices
Uses different colors for back and front of surfaces in LIGHTING_MODE
Added snap-functionality in PencilTool when drawing holes on surfaces
Length is now millimeter (because the . is not accepted in length field)
