[NTG-context] font style and size interaction

[NTG-context] font style and size interaction

[Hans van der Meer via ntg-context]

[-- Attachment #1: Type: text/plain, Size: 637 bytes --]

There is -- in my perception -- a problem with the interaction between font style and font size changes.
The order of calling for example  \it\small matters because \small\it leads to a different result.
I would however reason that size and style changes should be in orthogonal spaces, that is: the one should have no effect on the other.
Cause of this behaviour seems the \tf call included in small. See the accompanying example.

I can try to program around this, but I would prefer not to. Is there a possibility that this behaviour will be changed to \it\small and \small\it giving the same result?

\small does a (massive) bodyfont switch and therefore you end up with 
regular tf

Hans,

I see this as a no with respect to changing the behaviour of \small and friends. Which I can well understand: changes on this level may trigger a lot of unwanted problems.
But now I can program around it with a clear conscience;-)

normally for soem inline change where one doesn not have side effects 
(like interline spacing etc) \itx is okay as smaller \it (\itxx for even 
smaller sizes)

Of course you can go on an adventure trip:

test {\it test
     \glyphscale \numexpr \glyphscale * 700 / 1000 \relax test
     \glyphscale \numexpr \glyphscale * 800 / 1000 \relax test
     \glyphxscale \numexpr \glyphxscale * 3500 / 1000 \relax test
     \glyphyscale \numexpr \glyphyscale * 3500 / 1000 \relax test
     }
test
