odd flags in Pointer subtypes

[pixelzoom]

The subtypes of Pointer each have an odd flag that effectively identifies their type:

// Mouse
isMouse: true

// Touch
isTouch: true

// Pen
isPen: true

isMouse and isTouch seem to be the preferred way of determining how an interactive object moves at the start of a drag cycle. For example, in equality-explorer ItemDragHandler:

var yOffset = ( event.pointer.isTouch ) ? -( 1.5 * this.item.icon.height ) : -( 0.5 * this.item.icon.height );

Since none of these flags are defined in Pointer, WebStorm (and other IDEs?) complain that these flags are unresolved variables. For the above example in WebStorm:

Options:
• Live with the IDE complaint
• Define these flags in Pointer
• Get rid of the flags and use constructor comparison, e.g.: if ( event.pointer.constructor === Touch )

How about Mouse/Touch/Pen are cleaned up and we use pointer instanceof Mouse or similar statements?

Removed and refactored all usages to the suggested type above. Closing.
