This commit adds a buffer unrotate operation to DrawTarget. It's initially implemented with LockBits in DrawTarget. DrawTargetDual overrides the implementation to pass on the operation to it's DrawTargets. No override is given for DrawTargetCapture as we intentionally avoid this code path when async painting as it can fail. This is needed so that RotatedBuffer can expose a single DrawTarget, which can be a DrawTarget (for normal alpha), DrawTargetDual (for component alpha), or DrawTargetCapture (when async painting).
