I'm sorry to the bearer of bad news, but I see a very annoying issue with this patch. :)
The problem, is that we now have "virtual" events for real events, so in essence we get duplicated events. This is not an issue for programmers that listen to only one or the other. The problem is with HOLD and event propagation. For example, a scroller might HOLD/SCROLL a mouse down event, but the touch_event will not get that flag set, and some things will behave in a very weird manner. Enumi, raster, what do you think? -- Tom.
