Seems as if this startMouseCapture() and stopMouseCapture() could be
implemented by re-using DOM event's capture phase by adding event handlers to
the capture phase of the #document and then firing those events directly on
the target node.
In fact, I thought this was one of the primary use-cases for having the capture
phase in DOM L2 events...?

Hi, Cameron-

I found the mouse capture methods[1] from the old SVG 1.2 Full WD to be
useful when writing web apps that did drag-and-drop. Since they’re not
really SVG-specific, I suggest adding them (similar functionality if
not exactly as in that document) to DOM 3 Events. These are implemented
in Batik.
Thoughts?
SVG 1.2 is evil and breaks the Web, and therefore we should avoid
anything associated with it.
That said, I think it's a good idea, and I'd be fine with adding it, or
with putting it in a future events spec (along with multi-touch,
pen/tablet input, etc.).
Additionally, I've often wondered how the mouse sampling rate is
determined, and it might be interesting to expose that rate through an
API. In normal Web pages, this doesn't matter, but in Web applications
(particularly though with a lot of dragging, drawing, or other
mousemove-specific operations) it can help with performance.
