From: Max Horn <max@quendi.de>
Subject: New patch for OS X

Attached a .patch file for SDL/OSX with some nice bug fixes / enhancments.

* fixes the activation issues, which also caused the window to be
always drawn like an inactive. The close/minimize widgets now are
animated properly, too.

* the menu items are automatically adjusted to use the app name
instead of just "SDL App". I did this so that we really can use one
central SDLMain.nib file, w/o requiring developers to make a copy of
it and adjust it.

* libSDLMain now contains the proper cocoa code, not as before the
carbon code. This means apps no longer have to carry a copy of
SDLMain.m/SDLMain.h

* revamped configure.in to properly build a Cocoa/Quartz SDL lib, not
a Carbon based SDL lib
