Would be nice if an alternate version of fl_text_extents() were available
that could handle crlfs in the string.
Probably wouldn't be too hard;
Hm, doesn't fl_measure() do all this already?

Probably wouldn't be too hard; just need to break the one string
into separate lines, then run the existing fl_text_extents() on

No, fl_measure() measures typographical area,
whereas fl_text_extents() measures the 'inking area'.
These are very different.
See the test/unittests program, text rendering test for a
*Correction*
In particular how the two functions calculate differently the bounding
region
for the characters ('), (-), and (_); fl_measure() returns the *SAME*
x,y and height
for those characters, whereas fl_text_extents() does not.
Ah, I think I understand the difference now, will have a look at the test
tomorrow...
Though at now cannot imagine a use case for knowing the inking area.
Thanks for clarifying.

The problem is, it is not obvious what the right answer is, for a string

I actually needed this feature in my app, which coincidentally, was
also rendering musical symbols. I took the

@Ian, can't blame you -- impressed you took on fl_text_extents()
at all.. big job, multiple platforms!
But isn't the multiline issue simpler?
