I suggest that we use the "touchmove" event in these cases, for the following reasons: 1) It will probably be common for the shape and location of the touch point to change at the same time. I think it will be simpler to use a single event to communicate this, rather than two events. 2) Changes in size and orientation of the touch point are arguably a form of movement. 3) I do not forsee any problems caused by "touchmove" events that do not cause changes in the X/Y coordinates of a TouchPoint, especially since this already happens in the case where one touch point moves and another does not. > This could also potentially include the depression of the modififer > keys (alt/ctrl/meta/shift), even if those attributes are moved to > the TouchEvent interface as is being discussed in ISSUE-12. I think the user agent should *not* dispatch a "touchmove" event (or other touch event) when the only input is a depressed or released modifier key. Standard keydown/keyup events can be used for this instead.
