Touch Attributes
Each touch has zero or more attributes associated with it. Differing hardware is capable of reporting differing sets of touch attributes, so there is no guarantee that any or all of the defined touch attributes will bre present.

If the touch comes from a direct device (see GEIS_DEVICE_ATTRIBUTE_DIRECT_TOUCH) its position (x and y attributes) will be in window coordinates, otherwise it will be in the input device's own coordinate system.

GeisSize geis_touchset_touch_count (GeisTouchSet touchset)
 Gets the number of touches in a touchset.
GeisTouch geis_touchset_touch (GeisTouchSet touchset, GeisSize index)
 Gets an indicated touch from a touchset.
GeisTouch geis_touchset_touch_by_id (GeisTouchSet touchset, GeisTouchId touchid)
 Gets an identified touch from a touchset.
