[SDL] Mac & mouse buttons

Problem is that ctrl also exists on PC/Unix keyboards, so ctrl+click 
might already be used for something else. This problem doesn't exist 
with the Apple Key, as it is specific to Apple.

By emulating ctrl-click usually, yes. But then, most mouse drivers 
allow you to specify what happens upon a right-click. In fact, most 
even allow you to define it on a per-application base

I think it would be easy to add a compiler switch or so, that allows 
to use ctrlKey instead of cmdKey. Or maybe even turn off the whole 
thing!

Something like SDL_MAC_EMULATE_RIGHTBTN, and 
SDL_MAC_EMULATE_RIGHTBTN_MODIFIER or so...

But then you're dependent upon DrawSprockets, which is a bad thing 
IMHO - DrawSprockets *suck* *badly*!

Of course, this can be added, but please only optional.

Oh, and even better would be to add real InputSprocket support, which 
would allow the user to map keys/button as they wish :-) (is there 
Isp support in SDL yet?)


Bye,
