geometry shaders: make gs work with changable primitives and variable number of vertices

Browse Source 
lots and lots of fixes for geometry shaders. in particular now we work when the gs
emits a different primitive than the one the pipeline was started with and also
we work when gs emits more vertices than would fit in the original buffer.
