hi,

I have added an experimental opencv based camera module to svn.

Also added the vidcapture based one to subversion.

lib/_camera_opencv_highgui.py
lib/_camera_vidcapture.py


# with ubuntu you can install opencv like so:
apt-get install python-opencv

It supports more cameras than the current pygame module on linux - and
is theoretically portable to windows, and mac osx... however
python-opencv not easy to install on those platforms(mac,win).

I think these modules could be added as fall-back modules in case the
camera module is not working.  Or maybe even selected as a driver
option like how SDL_VIDEODRIVER can be used to select a video driver,
perhaps a PYGAME_CAMERA_DRIVER environment variable could be used.



cheers,
