- patch 2: fix 2 missing changes from 16 -> VNC_DIRTY_PIXELS_PER_BIT
[Wenchao]
- patch 3: fixed missing roundup of width in vnc_dpy_switch [Wenchao]
- patch 3: fixed x offset calculation in vnc_refresh_server_surface
- patch 5: fixed missing roundup of width in vnc_dpy_update, cleaned
up function
v2->v3: - fixed checkpatch warnings [Stefan]
- fixed an old coding style violation [Stefan]
v1->v2: - new patches 2,4,5
- patch3: added performance test [Anthony]
- patch3: further optimized the vnc_update_client by searching for the
next zero bit
with find_next_zero_bit.
- patch3: further optimized vnc_dpy_switch by using bitmap_set to mask
bits dirty.
