[SDL] Cocoa window menus in 1.3

[Sam Lantinga]

I have a nib-less SDLmain-less Cocoa setup in SDL 1.3, and I'm implementing
keyboard support now.  However, as soon as I take full control over the key
input, the window shortcuts in the menu will no longer work.

So my question is, should I put up a window menu for the default SDL app?
Should it respond to the keyboard shortcuts?  Should it also pass those
keys to the application?

Discussion welcome! :)

Thanks,
