TLUpdatePointerOptions

How to move the editor's idea of where the pointer is without a real pointer event having arrived.

The case this exists for is a change that moves the world under a stationary cursor — a camera animation, an undo that moves a shape, a page switch. The pointer has not moved on screen, but it is over something different now, and hover, hit testing and the active tool all need to be told.

SEMANTICS-ASSUMED: the fields. The docs name the options bag but not its members, so it carries the two things a caller can actually know — a screen position to use instead of the last one, and whether the update should run even when nothing appears to have changed.
