rhbz#968050
In contrast to Microsoft Msdn documentation, the iUniq of a SURFOBJ doesn't
always change when the surface changes. However, it seems that the
iUniq of the associated color_trans (XLATEOBJ) changes, while its
flXlate=XO_TRIVIAL. Since we tried to retrieve the alpha bitmap key
only by the surface iUniq, we fetched the wrong bitmap, and it looked
like parts of the screen haven't been rendered.
The patch modifies QXLGetAlphaBitmap so that it will use GetCacheImage
instead of duplicating its code. GetCacheImage was already fixed in
fc314927bc48835e to combine the iUniq of the surace and the
color_trans.
