> While again the core problem in this issue should be fixed, I would
think it should be possible to optimize the StyledEdit resizing somewhat.
For example if only the height changes, there is no need to recalculate
the layout, just show more text in the view. And in the case where the
width changes, to update what is shown it only really needs to recalculate
the layout from the start of the document to the view position (though I
guess the total height needs to be known to properly size the scroll
thumb.) But the whole thing should probably be done in a lower priority
background thread either way.

FWIW, none of this is StyledEdit-specific. That app is more or less a thin
wrapper around BTextView, which is where all of the aforementioned
optimization issues lie.
