What's new?
1. Some keys support by Leency.
2. New displaying model - real Phong - real not fake normal vector interpolation, normalising it and calculating
dot product (one for each light). It requires SSE3. (by me)
1. New displaying model - glass - it's two pass rendering. First pass calculates
Z position of all front pixels, second render image with adding reflective
component of light only for front pixels. Transparent effect by adding with saturation.
2. I removed bug with performing generation object after choosing 'emboss' option.
