TinyGL: Added gluDisk. Fixed args in gluCylinder and gluSphere (#223)

TinyGL:
- Fixed setting of `GL_FRONT_AND_BACK` mode;
- Fixed setting of `GL_SPOT_DIRECTION` angle;
- Optimization of drawing triangles and lines;
- Input parameters are adjusted to the OpenGL standard
  in `gluCylinder` and `gluSphere` functions;
- Added `gluDisk` function (the gluDisk function draws
  a disk-shaped quadric figure);
- Optimize function `calc_buf`.

Flag:
- Added lighting.

info3ds, info3ds_u, test_glu0, test_glu1, test_glu2,
textures0, textures1, textures2:
- Updated programs using `gluCylinder` and `gluSphere`.
