* Added submodule Window, including FileSelector and ImageSelector:

Most of the code comes from bpython/intern/opy_window.c, but two
    new functions were added, to access the file and image selector
    windows in Blender.

* Added submodules Draw (gui) and BGL (OpenGL wrapper):
    The code comes from bpython/intern/opy_draw.c, with minor changes
    to integrate it in the new implementation.

* Made changes to Camera, Lamp and Image submodules:
    The implementation was improved. These files should be good
    starting points for interested new coders to look at, now.

* Renamed interface.[ch] to EXPP_interface.[ch] to avoid conflict:
    There is another interface.h file in source/blender/include.

source/blender/python/api2_2x/modules.h
