Use client side arrays for GL_STREAM_DRAW attributes
Certain GPU/drivers are slow when using constantly changing
vertex buffers. They also run out of memory as the pipeline
the buffers so while a buffer is in used being drawn to they
can't delete it immediately when you upload new data to the
buffer.
This is an attempt to work around that issue seemlessly by
using client side arrays for buffers marked as GL_STREAM_DRAW
