Be careful, a 720 x 480 picture might crash a small memory system at full
resolution.

But, yes, to read every pixel you do not divide xPixels and/or yPixels to
get Resx and Resy. Those variables were added to make things go faster but
at the price of not doing exactly what I said, reading every pixel. Reading
every pixel is for later when I'm ready to make a highly detailed mesh. I
don't need it yet. I just need to know how ... which I do now.

If you want to read every pixel, you might consider a different image,
smaller.
Also, you might want to use ambient finish and turn off all the lights --
POV makes these light buffers that took a long time to do when I tried it.

In a couple days I'll be posting some code that will make the mesh and cut
holes in the picture.

Thanks for your interest. Maybe you can help me understand how to do what
I'm trying to do by keeping the questions coming.
