+Summary: Bitmap.RotateFlip: several bugs
+
+The attached test case exposes several bugs in Bitmap.RotateFlip.
+I'm using Mono and LibGDIPlus from CVS.
+
+Unzip it and start it with the arguments below listed. The program loads
+"hotfeet.gif", rotates or flips it and saves the result as "hotfeet2.gif".
+
+mono picrot.exe Rotate270FlipNone
+-> Segmentation Fault
+
+mono picrot.exe Rotate90FlipNone
+Content of pic is rotated, but width and height is not swapped, resulting
+in a garbled picture.
+
+mono picrot.exe RotateFlipY
+The resulting picture is slightly shifted horizontally, the right picture
+edge is suddenly on the left side.
+Quality of resulting picture is worse than the quality of the original.
+
+
+General problem: The transparency is never preserved.
+
+This all works flawlessly on MS.NET.
