after your last check-ins, things improved by numbers.
however, there is still one problem (at least on my system):
when using VBOs, any changes i make to the vertices (e.g. with
[vertex_offset]) are not uploaded to the card any-more.
is this behavious on all platforms ? since i don't see any
apple-specific things i assume so.
therefore i have added a vertexDirty flag to GemState (and GemCache...)
and rewrote setModified() for GemVertex-objects to set this dirty-flag
when apropriate to reschedule the upload.
this works quite well for me (but still might be sub-optimal...)

PS: i have removed all the vertex-objects from Geos/
