Oh, I'm sorry.. I thought only pictures were banned due to size.. Well, I'll
remember.

I see.. I thought gaussian blur would be useful because it's so big in
effect, and fast in assembly code.

I did.. I remember the different approches to reflection blur.. They all
shot additional rays and was not meant for blurring a simple bitmap..
However I didn't notice Chris's blurred pattern-posts until now.. Thanks..
Maybe this will find it's way into the next Pov version.. Anyway I learned
today how to code a convolution matrix.. I'm just amazed it works SO slow in
SDL.. In machine code, it's real-time for a fullscreen picture.
