#4 Modified GLUI

[Nick]

The version attached is a modified version of GLUI. The
modifications were done as part of the Doris project
(http://doris.sf.net). The modifications were done by
the user "bacontastesgood" (at sf.net). He is no longer
maintaining the code and so I am passing it over to you
to see if it is any use. It appears to be in the public
domain. You may find it of no use.

The code was modified some time ago so I forget all the
details of what was changed and why. I think the idea
was to add skinning and improve the rendering
performance. I've found however that I get some kind of
glitch which slows/stutters the framerate. Looking at
the history (which of course you can read on the Doris
SF project page), changes include:

• massive cleanup still, rearranged glui.h to avoid
  forward declarations, lots of variable renaming and
  general cleanup

• split glui.cpp apart, more general cleanup

• removed stdinc.h, added glui_private.h, removed
  global dependencies on string.h and stdlib.h

• • removed GLUI_String entirely
• renamed GLUI_Control::set_text to set_control_text
• retrofitted some more const correctness
• more general variable cleanup, renaming, scope control
• added buffer safety stuff (snprintf)

• moved some more constructors into C++ files

• • massive start of clean up, including switchin back
    to double buffered rendering, removing unused code,
    removing/replacing unnecessary types (RGBc, Byte, etc.).

• added hilite color

• migrated chunks of defines into enums

• started renaming and privatizing variables

I'm reverting back to GLUI 2.2 from this fork because
it breaks my script binding code (i.e. the API has
changed), and I don't want to have to support this fork
(e.g. the current stuttering bug for starters...).
