Dear Mr. Chris Huff

I am compiling Mega POVPlus0.3.1 under MrC in MPW.
under MPW MrC compiler work glow and #set function well and blob does not
crash.

use MegaPOVPlus3.01 files as follows and other MegaPOVPlus2.05 files
/***********************************************************/
glow.c
glow.h
lighting.c
vbuffer.c

/***********************************************************/
modify files for MegaPOVPlus2.05 to glow and #set
