10000l, the old code was slow as hell, copying stuff extra times and

actually broken -- blanking the whole screen at each 'page flip' with
-dr enabled. benchmarks:

before:
56% cpu for decode
56% cpu for vo with no -dr
25% cpu for vo with -dr

after:
56% cpu for decode
25% cpu for vo without -dr
0% cpu for vo with -dr

if vo_fbdev is going to do pageflip, it needs to do it for REAL, using
vertical scroll registers (like g2), not copying a temp buffer (which
will shear anyway and is super-slow).
