Satisfying rotated text needs

The most common technical graphic in the world
is the x,y data graph. Labeling the vertical
axis of such a plot needs +90 degree rotated
text. Implementing that (soon!) would satisfy
98% of the people asking about rotated text.
90 degree rotated text looks excellent with bit-mapped
fonts of course.
Oblique (non-90-degree rotated) text is used to
a much lesser extent, as in labeling of edges
of arc-node graphs, though some like to label
them with horizontal text.
As far as Postscript output goes, PS doesn't care,
as far as I know, what transformation you apply.
Most PostScript devices have resolutions that are much higher than
screen resolution (400 dpi is not uncommon), so arbitrarily rotated
text is still quite readable, if not good looking.
I vote for getting 90 degree text done real soon.
It is just a bit-remap, interchanging x and y
(and getting the signs right). Should not be
a big deal.
Somebody should take up the challenge. If I sound like I am personally
resisting the idea of implementing it, you're right. That's because I
would like to encourage CLIM users to write and publish things like this.
We deal with the biomedical literature and screen
versions of it. They only publish about 1,000,000
distinct data plots a year. Maybe we could start
saving some trees if we could move their stuff
to our silver screens.
