 Changed meta2tga to output correct colors.
+
+****** COMPATIBILITY CHANGE ********
+Changed local coordinate index from 32-bits to 16-bits, which requires
+that Radiance mesh files be recompiled.
+
+Changed integer tone-mapping routines to better deal with images
+containing large, constant regions.
+
+Improved interaction with rholo -o ogl driver under OS X, which was
+returning bad values from the depth buffer.
+
+Minor bug fix in ranimove where it was restarting processes when it
+didn't need to.
+
+Increased accuracy of default ambient parameters in rpict, rview, and
+rtrace.  In rad program, doubled -ar value, -ad value, and -as value,
+and decreased -aa value a bit.  Also adjusted -lr upwards and -lw
+downwards.  I should have done these things long ago, as processors
+have been getting faster and faster over the years.
