TinyGL:

- fixed setting of 'GL_FRONT_AND_BACK' mode
- fixed setting of 'GL_SPOT_DIRECTION' angle
- optimization of drawing triangles and lines
- fixes in 'gluCylinder' and 'gluSphere' functions
- 'gluDisk' function added
- optimize function 'calc_buf'
- clean code

Flag: add lighting

info3ds, info3ds_u, test_glu0, test_glu1, test_glu2,
textures0, textures1, textures2:
- updated programs using 'gluCylinder' and 'gluSphere'
