/**
 * Configures the global gesture configuration for the application.
 * 
 * Example:
 * ```
// Updates the `maxMoves`, `moveTolerance`, and `frequency` configurations while retaining the
// current value of all other configurations
configure({
    flick: {
        maxMoves: 10
    },
    hold: {
        moveTolerance: 32,
        frequency: 400
    }
});
```
 
 * Each type of gesture has its own set of configuration properties grouped within a separate object
keyed by the name of the gesture. Partial configurations may be passed and will be merged with
the current configuration.
 * 
 * `drag`
 * *  `boxSizing`  - The part of the component's box model is used as the bounds of the constraint.
Only applies when  `global`  is  `false` .
 * *  `'border-box'`  - the default, includes the padding and border but excludes the margin.
 * *  `'content-box'`  - excludes the padding, border, and margin.
 * *  `global`  - When  `true` , drag gestures will continue when leaving the bounds of the component
or blurring the component.
 * *  `moveTolerance`  - The number of pixels from the start position of the drag that the pointer
may move before cancelling the drag. Defaults to  `16` .
 * 
 * `flick`
 * *  `maxDuration`  - The amount of time, in milliseconds, to complete a flick gesture before it
is cancelled. Defaults to 250.
 * *  `maxMoves`  - The number of moves tracked to determine if a flick occurred. Defaults to  `5` .
 * *  `minVelocity`  - The minimum threshold, measured as the change in pixels over the change in
time per move, that must be exceeded to generate a  `onFlick`  event.
 * 
 * `hold`
 * *  `cancelOnMove`  - When  `true` , the hold is cancelled when moving beyond the  `moveTolerance` .
Defaults to  `false`
 * *  `global`  - When  `true` , hold gestures will continue when leaving the bounds of the component
or blurring the component.
 * *  `moveTolerance`  - The number of pixels from the start position of the hold that the pointer
may move before cancelling the hold. Ignored when  `cancelOnMove`  is  `false` . Defaults to
 `16` .
 * *  `frequency`  - The time, in milliseconds, to poll for hold events. Defaults to  `200` .
 * *  `events`  - An array of  `onHoldStart`  events which each contain a  `name`  and  `time` . The  `time` 
controls the amount of time that must pass before this  `onHoldStart`  event is fired and should
be a multiple of  `frequency` .
 * 
 * `pinch`
 * *  `boxSizing`  - The part of the component's box model is used as the bounds of the constraint.
Only applies when  `global`  is  `false` .
 * *  `'border-box'`  - the default, includes the padding and border but excludes the margin.
 * *  `'content-box'`  - excludes the padding, border, and margin.
 * *  `global`  - When  `true` , pinch gestures will continue when leaving the bounds of the component
or blurring the component.
 * *  `maxScale`  - The maximum scale value. Defaults to  `4` .
 * *  `minScale`  - The minimum scale value. Defaults to  `0.5` .
 * *  `moveTolerance`  - The distance difference from the previous distance that the pointer may move
before cancelling the scaling. Defaults to  `16` .
