refactored some of the initialization code
left place holder for Zoom in/out with pinch recognizer. The idea here is to make a virtual function like OnScroll for Zoom so we can take care of the zoom features natively.
reorganized some of the method declarations.
* Single Tap now implemented
* Touch and Hold (2 secs) to pop up menu
* added a pan gesture to simulate flicking up/down and left/right
* removed dependency on binding keys to game for iOS devices. (perhaps extend this to all touch devices.)
* flicking motion needs to be expanded to allow for smooth scrolling. Right now every flick is equivalent to going one slot up/down/left/right.
The problem was, the game would initialize first, reading the
keybindings from the configuration, and THEN set up the default key
bindings.
I think this affects only PSP, X, SDL and Qt. A quick scan of the
windows version code looks to me that the order is correct and the
problem should not exist, but I may be mistaken. The iPhone version
looks to me like it has no keybindings at all, though the call is
there ; I put the call in the right order so that the problem does
not happen in the future if we implement some key bindings for it.
If someone can check for windows...
* pruned out unused local variables.
---- There's no need to define something if it isn't going to be referenced. It consumes extra memory temporarily and more than anything is a potential cause for confusion down the road.
