Yes, that's right, the call to get scale from the sizeInMatrixSpace: 
method needs to be moved up front.

That's perplexing, PSrotate(90) gets me text that moves up the screen. 
This is on a x86 processor.

A question: the xvertext routines first render the text horizontally, 
then scale it, and finally rotate (this sclaed text). I am somewhat 
unclear as to whether this is how it should be done - especially as 
PSscale() and PSrotate() do not commute. Thanks for any wisdom.
