* 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.
