Cool!  I hope your thesis went well! ;)

Ooh!  Interesting!

I think the difference is that Tux Paint 0.9.14 accepted ANY mouse button,
whereas 0.9.15 only accepts left button (button1), unless the
"nobuttondistinction" option is set.

It seems Mac OS X or SDL are sending Tux Paint middle/right, if
option/command are being held.  And thus, Tux Paint is ignoring them.

I'll look about allowing middle/right clicking for anything that also
accepts [Alt]/[Option] key, so that it works right on Mac again.

I'll look over the code to make sure that it SHOULD. ;^)  I'd appreciate
it if you could test, though.  Thanks!
