Re: [MAC_OSX] Patch for Mouse-wheel, Multi mouse-button support & more

Hi Everyone,

I have just checked in Steven Tamm's fix to allow keys to be first
passed to the Mac Toolbox for processing before they are seen by Emacs
while USE_CARBON_EVENTS is defined.

This is important for people using a Mac OS input method, e.g.,
because command-space is the script switching key and must be seen by
the Mac Toolbox.  Also control and command key combinations are used
to set different options for the input methods.

I have also introduced two new variables mac-pass-control-to-system
and mac-pass-command-to-system, whose values determine whether keys
typed with the control and command keys, respectively, are passed to
the Mac Toolbox.

They both default to t so the behavior should be identical to the code
before USE_CARBON_EVENTS was introduced.

Andrew.
