I did some render tests with the patch that Daniel JUNGMANN sent me some
time ago.
I used six different executables to render 4 different scenes

The executables :
1 - My own compile with Daniel's patch. I have the Microsoft Visual
Studio V6.0 C++ with the latest service Pack and the preprocessor for
AMD's 3DNOW!.
2 - The binary sent by Daniel
3 - The original POV 3.1 program.
4 - MegaPovPlus05aplusmod032 ( compiled by Jeff Biermann with Chris
Huff's patch)
5 - MegaPovplus for Linux ( compiled with gcc)
6 - Povwin running with wine under Linux


The render settings were +w640 +h480 -f +a
My computer is a Duron 700 Mhz, 256 Mo running with Windows Me and Linux
2.2.17.

One thing though, the glass objects were rendered in a violet color with
my own compile of Daniel's patch.
It seems that in some cases, the patch can be faster.
