Added an enable/disable intro music option.
Added an enable/disable instrument panel option.
Added an enable/disable mouse pointer option.
Added using namespace std for compilers that support this.
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.
Mesa/glu version.) But, by calculating the Model View matrix our selves
we can save this matrix without having to read it back in from the video
card. This hopefully allows us to save a few cpu cycles when rendering
out the fragments because we can just use glLoadMatrixd() with the
precalculated matrix for each tile rather than doing a push(), translate(),
pop() for every fragment.
Panel status defaults to off for now until it gets a bit more developed.
Extract OpenGL driver info on initialization.
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.
Added a command line option to specify fov.
Adjusted terrain color.
Root path info moved to fgOPTIONS.
Added ability to parse options out of a config file.
