--- Comment #39 from max@veneto.com 2008-09-21 06:32:37 --- Another finding.... The text I was looking into had a very small (1e-9) z coordinate, which made it to go through PATH_ExtTextOut() routine, with the problem above (shrinking of text depending on screen position). That's another bug, probably texts with non null Z coordinate are handled differently by autocad. So, back to previous problem, with normal text. I'll file another bug report for the problem above on next days.
So, by now I'll look again for codepath used for drawing normal texts on autocad window.
