I didn't try right-to-left text until now --- thanks for prodding --- = and the behaviour was predictably awful.

E.g., we may need a condition that verifies that this is a > TAB (should be easy by looking at glyph->object, I think). After some false starts, I settled on the simpler = 'fine-grained-mouse-movement' solution, giving pixel-wise events no = matter what the mouse is pointing at. The extra cost for this is = imperceptibly slight, and it feels more generally useful than the = 'mouse-movement-in-tab' thingy. --Apple-Mail=_5926568B-CC72-46C5-81FF-D36ABB7B2433 Content-Disposition:
