Subject: Added pbuffer support to JOGL on X11; HWShadowmapsSimple and
ProceduralTexturePhysics demos are now working on Linux with the appropriate
hardware. Moved core GLX routines out of the public GLX interface; this
allowed XVisualInfo (and the new GLXFBConfig) to be removed from the public
API. Added support to GlueGen for returning arrays of pointers as arrays of
StructAccessors in Java and for choosing the typedef name for a
pointer-to-struct if the struct itself does not have a typedef name. Added
support to GLEmitter to emit ProcAddressTables under arbitrary names and to
support arbitrary mechanisms for fetching those tables. Made GLU (on all
platforms) and GLX (on X11) be dynamically linked. Refactored
ProcAddressTable filling to be mostly shared code. Tested changes on Linux,
Mac OS X and Windows.
