Whats new in 38 ver??
 
1.  Save to ply format..
2.  /Next edit/ - possibility to edit-deformate part of object 
     selected by tess area.. 
3.  Long pipe - possibility to Catmull Rom spline based...
4.  Possibility to generate object with wall based on rotated
     splines ...
5.  Generate Mandelbrot fractal as texture option...
     Its multithread, but unoptimized..
6. 'From tex' button - allow basic convertion pixels <-> voxels
    from texture. Black 0x00000000 color is treat as transparent..
    I need make checking if texture is not to complex to convert...
7. New couple radius-rotary axis calculating in L pipes generator.
    This allow prodcing pipes with smoother surface..
8. 'March shd' button. - > Attempt shadow calculating through
    ray marching - not work properly (should work in glass + texture 
    model ... 
Other (minor) changes:
   - AVX attempt of real phong routines...
      (now switched off)
   - Bezier patches - correct 'z' vertex..
   - 1 face object correct edge calc..



Bugs:
Bugs, I noticed:

- problems with submit FFD cage modified object when only one 
  selected  chunk is processed...
- chunk no '0' problems... sometimes one chunk alone triangle ..
- not always corrected saving to 3ds file - always press 'sort chunks'
  button before sving object above 65535 elements ..
- weird edges detecting - unstable edges count info...
- Blender saves corresponding 3ds file with one more face than win3ds..
- merge vertices on selected chunk not work...
- hrt objects/l pipes/Bez patches, crashes if are switched too many
  times. Even 2-3 times is enough to crash ..
- Ray shadow not work...
- Bezier patches -- 
- tesselate (besides chunk tess) --
 
  NOTE - app unstale - regularly press saving buttons to prevent
  data loose....
