Better checking for xmesa/fx 3dfx fullscreen/window support for deciding
whether or not to build in the feature.
Translucent menu support.
HAVE_AUDIO_SUPPORT -> ENABLE_AUDIO_SUPPORT
Use fork() / wait() for playing mp3 init music in background under unix.
Changed default tile diameter to 5.
Mesa/3dfx/glide.
Added a basic splash screen. Restructured the main loop and top level
initialization routines to do this.
Hacked in some support for playing a startup mp3 sound file while rest
of sim initializes. Currently only works in Unix using the mpg123 player.
Waits for the mpg123 player to finish before initializing internal
sound drivers.
Shuffled some additional view parameters into the fgVIEW class.
Changed tile-radius to tile-diameter because it is a much better
name.
Added a WORLD_TO_EYE transformation to views.cxx. This allows us
to transform world space to eye space for view frustum culling.
