From: Bob Ippolito
Subject: [SDL] SDL_QuartzWM patches

I've sent in two small patches to SDL_QuartzWM directly to Sam over the
past few months (well, I think I sent both anyway) and neither of them
have been implemented.  I didn't receive a response, so I'm sure he was
just busy and/or they got lost, so I decided to sign up to the list and
post them here.

This patch rolls both of them together:
- Mouse cursor becomes visible if hidden when it moves outside of the
game window.  If you want it to stay invisible you should warp it
because if it's not warped a user might click some random other
application!  Commercial games behave in this way (or at least Warcraft
III does, which is the only one that uses a custom mouse cursor and no
warping that I've played in recent memory).
- Right mouse button emulation is changed from Command-Click to
Control-Click, which is how OS X behaves.

Consider copyright assigned to whomever needs it under whichever
license it needs to be under.. yadda yadda yadda.
