Re: Mouse Capture for Canvas

Sorry I don't have anything to add to the main discussion points but I want
to point out that this should NOT be limited to the canvas tag.

There are whole game engines that work on nothing but manipulating DOM
elements with z-index and setting style.left and style.top.  I can imagine
plenty of other apps that don't use canvas that might benefit from
mouselock.  A mapping page. A graph exploration page. A photo viewing page.
