From: Dave Airlie <[email protected]> This reverts commit 77c7a64e8885696665556c9fbcb3cffb552e367a.
It looks like this was being used to workaround some bug in the Intel driver cursor handling, so instead of fixing the driver, the server got hacked and this broke rotation on Intel and everything else. So revert this, and hope Intel can actually locate the problem in their driver. with this reverted, rotation on -ati works again, no one-pixel overlap, the cursor can go the whole way to the edge. On Intel, no one-pixel overlap but the cursor has an off-by-one in it.
