Color matrices

• Sphere ColorMatrix object used to transform colors
• CreateColorMatrix(rn, rr, rg, rb, gn, gr, gg, gb, bn, br, bg, bb): Creates a ColorMatrix that is used to transform the colors contained in a pixel with the following formula:

  newcolor.red = rn + (rr * oldcolor.red + rg * oldcolor.green + rb * oldcolor.blue) / 255;

  newcolor.green = gn + (gr * oldcolor.red + gg * oldcolor.green + gb * oldcolor.blue) / 255;

  newcolor.blue = bn + (br * oldcolor.red + bg * oldcolor.green + bb * oldcolor.blue) / 255;
