Details

As I understand it we currently just use glBufferData. On Mac it looks like this causes an allocation each time and we can end up spending time pagefaulting the new allocation because of zero-fault-on-demand. Using glBufferSubData seems to avoid this problem.

Blocks: wr-67

I think we actually currently do this appropriately. I'll close for now.
