Fixes#141, "Main menus on POD and Speed Devil show up black"
Seems like the TA doesn't touch any of the memory structures before first write (and probably later on, but we're not gonna support corrupted ta streams for now)
According to p1pkin
«At least in SpeedDevils, at title screen game do a bit weird thing
- Init TA context
- Send lists to TA
- Init the same context again
- Start Render
so, if you are clear stored poly/vertex data at "TA_LIST_INIT" pvr2 reg write - you'll get black screen instead game title»
- Clipping is done on the SH4 side, garbage might be outside the screen
- Mod vols aren't drawn anyway for now
- I wonder how much does this cost on the rend-thread?
- make ta_skip to ta frame skipping instead of skipping parsing entierly. it handles 1 out of every (N+1) frames.
- re purpose rend to unstable opts, as pvr.rend is of no real use right now
