[Python-3000] PEP 368: Standard image protocol and class

[BJörn Lindqvist]

Cool PEP! I really love the API for the Image class. A standard Image
class would be a useful addition to the standard library.

But I cannot see how it would solve the problem with to many image
classes. The reason why PIL, PyGame and wxPython has different image
classes is because each of them use different C functions for
manipulating said image classes. These differences bubble up through
the bindings and results in PIL exposing an Image, PyGame a Surface
and wxPython a wxImage. The result is that if you want to use a PIL
Image in say PyGame, you  still need to convert it. If PIL stores RGB
images with 32 bpp and PyGame uses 24, then you'll have to convert it
to get it into the proper format.

The only way to get compatibility between the libraries is to create
an image library in C _and_ get those libraries to start using it.
