I added gl-x11 which allows compatibility with X11 (Xlib-based) and GLX.
I also added various functions to handle file finding based on FHS.
Various changes to autotools to both install files correctly and to configure correctly.

In particular, it removes any deprecated functionality
wxWidgets only documents their deprecated m4 macros and gives a poor example
Also to note in regard to wxWidgets, I removed any unneeded libraries from the linker line.

Any warning messages provided by autoconf has been supressed in the most appropriate manner possible.
