View3ds 0.056 - tiny viewer to .3ds files.

What's new?
1. MMX optimizations in 2tex mode (file two_tex.inc).
2. Tiny SSE optimizations (file BUMP_CAT.INC).
3. Bit (two instructions) improved random light generation procedure.

Buttons description:
1. rotary: choosing rotary axle: x, y, x+y.
2. shd. model: choosing shading model: flat, grd (smooth), env (spherical
   environment mapping, bump (bump mapping), tex (texture mapping),
   pos (position shading depend), dots (app draws only points - nodes of object),
   txgrd (texture mapping + smooth shading),  2tex (texture mapping + spherical
   environment mapping), bmap (bump + texture mapping),  cenv (cubic environment
   mapping).
3. speed: idle, full.
4,5. zoom in, out: no comment.
6. catmull: on( use z buffer ( z coordinate interpolation), off( depth sorting, painters
   alghoritm).Txgrd, 2tex and bumptex models only with catmull  = on.
7. culling: backface culling on/ off.
8. rand. light: Randomize 3 unlinear lights( so called Phong's illumination).
9. Blur: blur N times; N=0,1,2,3,4,5
10.11,12,13. loseless operations (rotary 90, 180 degrees).
12. emboss: Do emboss effect( flat bumps ), use blur to do edges more deep.
       carefull with emboss + fire - it looks annoying.
13. fire: do movement blur ( looks like fire ).
14. move: changes meaning x,y,z +/- buttons  ->  obj: moving object, camr: moving camera.
15. generate: Generates some objects: node, Thorn Crown, heart...
16. bumps: random, according to texture.
17. bumps deep -> create bumps deeper or lighter.
18. re-map tex -> re-map texture and bump map coordinates, to change spherical mapping 
    around axle use 'xchg' and 'mirror' buttons, then press 're-map tex' button.
