New commits: commit 4e93ac7f5c2b6a438f384a0f22ae0c18c1d73c0e Author: LuboÅ¡ LuÅák <[email protected]> Date: Tue May 28 14:10:46 2013 +0200 fix emf transparency handling (bnc#820385) 46e53913e9dcc84ffed8fb5f1b4959c70c7e5649 fixed some transparency emf problems on X11, it however did it by implementing alpha support in X11SalBitmap only and made generic code rely on it. Now it doesn't work at least on Windows, after reverting it works on Windows but not on X11. As I have no idea what the real problem is, at least keep both code paths.
