Touchscreen pinch events can't happen on the main thread right now so this is
all dead code for now.  I'd prefer we removed the pinch-related parts of this
patch and revisit when main-thread touchscreen pinch actually has a working
implementation.

Not sure what this has to do with the rest of the patch?

Removed pinch handling logic/tests for not and returned this to previous state.
