Determines which, if any, of the handles are pressed given the touch coordinates, the bounding
box, and the touch radius.

@param x the x-coordinate of the touch point
@param y the y-coordinate of the touch point
@param targetRadius the target radius in pixels
@return the Handle that was pressed; null if no Handle was pressed
