TODO now there seem to be two buffers of VSC data (both referenced by
CP_SET_BIN_DATA packet. Not sure what this new DATA2 one is, but seems
to have the larger pitch.
+
+ The "DATA2" buffer is probably actually the main visibility stream; it
+ is at least the larger of the two.
+
+ For VSC_DATA_PITCH, 0x20 actually seems to be sufficient (although blob
+ uses something somewhat larger) for many cases, although required value
+ can ramp up somewhat higher. Values less than 0x20 trigger GPU hangs
+ even with small amount of geometry (so possibly 0x20 is minimum
+ alignment or something like that). So far I can't seem to find any-
+ thing that needs values larger than 0x20
