Subject: added mipmaps for the hw renderer, improvements

This commit add mipmaps, but for now, mipmaps are generated on the gpu
at runtime. We should generate them in advance.

- added mipmaps for the hardware renderer
- renamed stb_image.c to stb_image.cpp
- add compiler flag to stb_image.cpp to prevent warning
- added pipe notation for various objects to have all clipping functions
  be left to right. We need this for the time being because dot notation
  would considerably complicate the current implementation
- small improvements
