Asm: 4*4 Matrix Multiply

[Petr Schreiber]

Thanks a lot Charles,

I used multiplication only, as in 4x4 matrix all can be saved - scale, position and rotation.

The problem i have to deal with, is that modern digital photographier produce so huge image, that wanting to perform cumulative settings in real time even with assembly, seems to have reach a limit, that could not be further optimized without the help of a graphic accelerated hardware.

Thus i think it is better to use a preview using a small size (for example 512x512) to adjust the settings, then apply them to the real photography once all parameters have been set.

Anyway if ever you can push the limits furthermore with these FPU settings i would be glad to try it
