[SDL] Inverted y-coords in OS-X

The subject kind says it all : SDL is feeding me y coordinates which 
increase from zero at the bottom of the screen, when running in a 
window on OS-X. I know Cocoa is 'inverted' compared to Quickdraw / GDI 
/ X11, but I'd assumed this is the sort of thing SDL would abstract 
out?

I have verified the program behaves fine on Linux, and also that it's 
the actual numbers from the SDL events that are flipped

I searched for similar issues and found one message to this list by 
Brian Hook, describing what sounds like the same problem : but that was 
the middle of last year. I know lots of people are using SDL on OS-X, 
so why is it only me seeing this problem?

OS-X is Panther 10.3.1
SDL is 1.2.6, compiled as a framework

Hoping for enlightenment....

PS - I have another odd OS-X issue no matter what I do, SDL won't send 
me SDL_VIDEORESIZE events (and the window Surface is indeed being 
created resizable). I can cheerfully resize the window using the mouse, 
but the SDL app never gets told about it. Again all is fine on Linux.

There is no such thing as a humble opinion.
