Another shadowbuffer goodie: the "Halfway trick"
http://www.blender3d.org/cms/Shadow_buffer__Halfway.786.0.html
Simply said: by using the average of the nearest and 2nd nearest Z value
in Shadowbuffers you can reduce bias errors very well.
For backwards compatibility it is a new buffer type though.
