Update of /cvsroot/bprocessor/gl/src/net/sourceforge/bprocessor/gl/tool
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv3390/src/net/sourceforge/bprocessor/gl/tool

Modified Files:
	AbstractTool.java PencilTool.java ToolFactory.java 
Added Files:
	CameraTool.java 
Removed Files:
	RotationTool.java CameraZoomTimer.java CameraMoveTimer.java 
Log Message:
removed the two timers from the system and added a renamed rotationtool to cameratool. Changed camera rotation so that it uses the geometry class from the model package. It is now relatively good rotation and drag in the right directions. The are one question ralated to horizontal rotation either we shall rotate about the z-axis or the up vector, as it is now I use the up vector but that makes rotation a bit wird in some situations. If we choose to use the z-axis we cant rotate if we look from above.
