[DGD] call touch

[Shentino]

I'm pretty sure about this but I wanted to double check.

When an object is touched, the touch flag remains in effect until a
call is made on the object

Then the touch flag is cleared, driver->touch(obj) is called, and if
that returns true, the touch flag is reapplied

And then the original call is made.

Questions:

1.  Is this accurate?
2.  Can driver->touch(obj) recurse if you retouch the objec tthen call
it before returning from driver->touch?
