That's still a TODO for now; in either case, I'm very loathe to put it
in the spec, and would like to have the emulation pointer-dependent.
The resulting pointer events will have the TouchPointer (although this
will probably be renamed to something like PointerFromTouch to avoid
ambiguity with touch event flags) flag set, indicating that they came
from a touch event.  Would you like the touch events to have a flag set
indicating that they are also generating pointer events?

To be honest, I haven't really thought too much about pointer emulation
- Chase or Peter might have some more thoughts on this.
