303405 - Dispatch an event when the text zoom level changes

Status: NEW

Description

I think it would be useful to dispatch an event whenever the text zoom level
changes. DHTML widgets might need that information to refresh themselves.

See also bug 229015, "OnResize event should fire when Text Zoom level is
changed" (wontfix).

There's another similar problem.  When the tab bar appears (due to going from
one tab to more than one), the display area suddenly gets smaller, but there's
no event.

Yet another event is when scrollbars appear.  Suddenly the display area gets
smaller.

Ideally all these would be addressed at the same time.  Onresize seemed to be
the logical event, but others disagree.
