I see, I'll let the libsdl folks know, and see what they think about
that. The get_mouse thing might work for teh stylus, but not for
multi-touch :(
Is there a way to inject code, or attach handlers to the actual
underlying system window (instead of teh SDL abstraction) from python?
SDL must handle the windows mesage somewhere, but I dont know if that
is accessible at all through python. i tried using win32 hooks, but I
cant inject python code (the code has to be in a dll). I dont really
want to change the code in C/C++, because it would require user to
compile a custom version.
