Convert all consecutive calls to d7_DrawPrimitive(TRIANGLE_FAN) into
a single call to d7_DrawPrimitive(TRIANGLE_LIST) with all the vertices.
Note, it *increase* the number of vertices, but bandwith is much less costly
than multiple calls.
Note, only a very precise subset of the calls get buffered in order to
ensure that the disruption is minimal.
