[PATCH 0/1] MR2543: winemac: Don't constrain surface dimensions to the onscreen part of a window.

[Brendan Shanks (＠bshanks)]

Fixes an issue where a window's image would be stretched as it was moved
further offscreen.
The offscreen part of a window also did not display correctly in Exposé.

Note that the reason for doing this is that some apps create huge windows (like 32,000 x 32,000). Without additional constraints this would create a 4Gb surface.
