Re: Font issues

[Fred Kiefer]

David is correct about the toy API of cairo that we are using.

Do I understand you correctly that the only problem you have is with the font 
metrics, that the letters get positioned at the wrong points. Or is there 
something else that you don't like about the way we currently display text?

The reason for the metrics problem is most likely a cairo bug that I reported 
sometime ago. In cairo fonts get cached internaly and we may get back a font 
object for a different size then the one we request. The cairo developers 
didn't see this as a probelm worth fixing, as it only seems to affect GNUstep. 
Maybe because we use the toy interface.
