+// Did some serious horsing around to be able to "hug" the ground properly
+// and still be able to take off.

+// ground.
+// Did some serious horsing around getting the initial airplane position to be

+// dropping below the terrain, even when the flight model doesn't quite
+// put you as high as you'd like.

+// 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.
+//
+// Revision 1.29 1998/07/04 00:52:22 curt
+// Add my own version of gluLookAt() (which is nearly identical to the
+// 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

+// Added a WORLD_TO_EYE transformation to views.cxx. This allows us
