// Optimization idea:

// 2: Only pass x/y values in the movement routine.

// The only "bad" thing is that it could break old code.
//
// Future thoughts:
//
// The extra space gained can be used for a generic mouse event that can be called
// when there are _ANY_ changes. This one you _MAY_ want to pass everything, however the
// sketch could already have noted these facts to support drag/drop scroll wheel stuff, etc.
//
// Why do we need to pass the structure for buttons?
// The function call not enough of a hint for what is happening?
