[PATCH v13 0/6] MR2105: ddraw: Add local buffer in d3d_device7_DrawPrimitive()

[Steve Schnepp (＠steveschnepp)]

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.
