[lively-kernel] iPad: mouse vs touch events

[Dan Ingalls]

Hello Werner -

I've just been trying to sort this out, and I've just checked in some useful code in the repository, but I don't have it all working just right.  At least you will find
	UserAgent.isiPhone   // a boolean you can test
	UserAgent.iPhoneDragMode();    // Makes LK receive mouse move events
	UserAgent.iPhonePanMode();    // Leaves touch events going to OS for pan/zoom

In addition to the Apple link you cite, I found this to be useful...
	http://rossboucher.com/2008/08/19/iphone-touch-events-in-javascript/

I think I'm pretty close.  At least, when I get into drag mode, I can click on things and drag them, and when it's in pan mode, the OS does the right stuff.  My first goal is just to get it working so that if you click in the world, it will go into pan mode, and if you click on anything else, it will go into drag mode.  But apparently mouse focus (which I'm using) doesn't often get set when dragging things (I need to review this).

I don't have an SDK, so I'm using an iPhone to test.  I've just checked in qtest.xhtml that loads much faster (includes a recommendation for localconfig as well).

I hope this helps.  Please let me know if you have any more success.

	- Dan
