Um... how about full support for POV-Ray's SDL? jk ;D

It works on my laptop (hardware is two AMD A6-4400M APU 2.7 GHz processors w/
integrated Radeon HD 7520G GPUs [not particularly bragworthy]) using Firefox
(see attachment). IE couldn't initialize shader1, but it did display the samples
counter.

I'll have to look into reusing samples again. My sole attempt used a 32 bit RGBA
texture (unsigned 8 bpp), but it never converged into an acceptably noise-free
result. I figured if I used a higher bit depth I might get better results.
