 GdipSaveImageToStream.
 
 Please feel free to modify the declaration of GdipSaveImageToStream.

 unnecessarily.)

+HandleRef was not supported in Mono in the first place (until a few
+minutes ago, ie, nothing before Mono 1.2.4)
+
+Any code using HandleRef in System.Drawing was never tested, you would
+get garbage.
+
+Currently with SVN/trunk and HandleRef support, am getting this crash,
+which seems to be something else:
+
+mono$
+mono$ mono --debug /tmp/fi.exe
