+
+* The boolean value returned via the last parameter to XShmQueryVersion()
+ isn't honoured everywhere.
+* The init functions that take parameters allow the caller to enable shared
+ pixmaps when they aren't supported (or disabled by configuration files).
+
+
+These result in incorrect rendering when the MIT-SHM extension doesn't support
+shared pixmaps, e.g. using EXA with current versions of Xorg.
