Re: [pygame] BUG: Different events when I enable OpenGL

[Thomas Hansen <thomas.hansen@xxxxxxxxx>]

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.
