Thank you for this clarifying information. It sounds like the problem
is font requests are communicated from app to system in terms of
point-size instead of some pixel-based metric. Assumedly pixel-based

API, correct?
Nope. It also wouldn't help. The hard-coded coordinates are measured in
points, too.
Anyway, although neat flamewars are possible based on this, I'll just
state my recommendations:
1. Create auto-sizing interfaces.
2. Design for Vera Sans (since Vera Sans is large enough that most
other fonts, and at least all standard choices for system font, will
fit).
(Also, 3. just leave, say, 20% extra space for labels in UI no matter
what.)
Well, that's not _my_ recommendation, but if there's space and there's
no visual impact, there's no reason not to. :)
I don't want to ignite any flames, but I wonder if there is an
alternative. ;-) While (1) is ideal in theory, in practice we have a
framework (appkit/gui) and interface design tool (IB/Gorm) that have
long made fixed layout their bread and butter. Even if we make a
conscious decision to use more autolayout, and manage to convert our
existing apps, problems will still come up with porting. (2) would also
have this problem.
You mean that the interfaces would have to be redone? In practice, you
have to do that anyway, so I don't think that's a significant problem.

I'm not sure what you mean here. R is auto-sizing, and if you use code,
you can either use auto-sizing or do what'd you do for Gorm (ie. design
using Vera Sans; you don't have to use when the design is done).
We could try going the OS X route, where you basically cannot set system
fonts, and provide a fixed set of default fonts packaged with
gnustep-back for each back end. This limits user choice.
I don't think that would be acceptable.
But what about this possibility instead: is there some point within the
text rendering pipeline for gnustep that a metric measurement could be
made, and if a mismatch exists between pixel-based size of the
designed-with font and the size of the runtime candidate with same point
size, the runtime one be substituted with a sufficiently smaller
point-size version? This would be done once per font request, based on
a fixed, representative string.
[snip]
There are no pixel sizes involved anywhere, but you could compare the
width (in points) of some suitable string. However, I don't think this
scheme would be worth the trouble. I consider auto-sizing to be the
solution, and, failing that, making things big enough for Vera Sans
makes them big enough for most other fonts.
(Note that you could achieve something similar manually by just setting
the NSFontSize default.)
