Does both FrameMaker and XFig use this technique? XFig can place text at 1
degree increments. Could this be implemented (without undue pain)
independantly of Tk using the xfig code as a starting point? CAD with out
rotated text is, uh, well it ain't CAD!

The file hints that BLT
can do rotated text. Anyone have experience with this and STk?

I also found this comment on

"I've heard that X11R6 can draw rotated text, but I do it the hard way
much like BLT (which inspired me, so thanks to!"

So I guess that X11R6 is able to draw rotated text so maybe this problem
will go away in time.


Thanks much,
