- buffer offsets in the base regs are 256b aligned so
shift properly when comparing, fixed by Andre Maasikas
- mipmap size was calculated wrong when nlevel=0
- texture bo offsets were used after the bo base address was added
- vertex resource size register is size - 1, not size

I tried this patch on a d-r-t from 100805 (todays d-r-t seems to have reverted to a month ago and doesn't work well with tiling)

The patch, while fixing mesa demos lodbias and cubemap, seems to regress ut2004 and doom3 demos -

radeon 0000:01:00.0: mipmap bo too small (128 128 4 0 7 393216 -> 458816 have 655360)
