+
+4/23/98 - encapsulate all #include <config.h>'s with #ifdef HAVE_CONFIG_H
+
+4/23/98 - Give all textured polygons ambient and diffuse glMaterial()
+ properties of "white" so GL_MODULATE works as expected and
+ textures are not oddly tinted.
+
+4/21/98 - Convert lighting equations to table lookups
+
+4/21/98 - Make sure all #ifdef _cplusplus are after any other includes
+ Make sure all .hxx files have #ifndef cplusplus #error
+
+4/21/98 - various autoconf cleanups/preparation for C++
+
+4/9/98 - Fixed a bug in event management where the next event run time
+ was miscalculated so it was never run.
+
+4/6/98 - Cleanups
+
+--------------------------------------------------------------------------
+
+4/3/98 - Released version 0.40
+
+4/3/98 - Incorporated the Gnu automake/autoconf/libtool system.
+
+3/17/98 - Fix time jumping problem on win32
+
+3/1/98 - Unify sun position render code with existing sunpos
+ calculations so the sun doesn't do it's little jump every
+ hour.
+
+2/19/98 - Fixed a problem with smooth view (scenery center) switch
+ when entering a new tile.
+
+2/18/98 - Fixed a problem with terrain generation that was causing

+
+2/2/98 - Fix warning when compiling with c++ ... also successfully built

+12/17/97 - Released version 0.18
+
+12/17/97 - Fix sun/moon initialization code so display lists aren't

+ * A simple clear-screen sky.
+ * No fog.
+ * No astronomy.
+ * Less detailed terrain.
+ * Texture - but no MIP-mapping.
+ * Texture - but no bilinear blending.
+ * No texture.

+12/29/97 - sky tweaking
+ Steve Baker writes:
+ So, by building the sky in the flattened shape, we can have it be
+ very foggy at the horizon and clear blue overhead.
+
+ The other important feature of this model is the colours. We
+ colour each vertex of the dish individually to allow for cute
+ sunsets, a darker blue overhead than at the horizon in daylight, a
+ gradual darkening of the sky as a function of altitude for very
+ high altitude flight - into space. Also we tint the horizon more
+ in the direction of the sun so that sunset starts where the sun
+ goes down - and the sky remains blue on the opposite side of the
+ sky - then as the sun gets lower, the colour spreads outwards all
+ around the sky and the black of night creeps in slowly from the
+ opposite side of the sky from the sunset.
+
+ We also like to tint the bottom edge of the sky with white - even
+ in broad daylight - so it looks fuzzy - even when there is very
+ little fog to achieve that effect.
+
+ We use a text file that contains a lookup table relating the sun
+ angle relative to the horizon to:
+
+ * The colour at the top of the sky dome,
+ * The colour of the horizon nearest to the sun
+ * The colour of the horizon farthest from the sun
+ * The colour of the texture environment blend for the clouds.
+ * The fog colour.
+
+ We can then tweak that file to set up all the conditions. The
+ realtime system interpolates the horizon colours all around the edge
+ of the sky.

+12/29/97 - Ground collision detection
+
+12/29/97 - glut windows or something for panel area - consider 3d
+ panels, careful of texture memory problems.
+
+1/5/98 - bzflag sound code might be able to work for us.
