Problems with rotated text (monospace font only) - starting with version 2.3.5
I think I discovered an interesting bug connected to rotated text with libxft version >= 2.3.5. It appears only when monospace fonts are used.
Symptoms (see also the attached demo program xft-example.c): A Rotated text string will not be printed with the requested angle (while the individual characters seem to be rotated correctly). In the example the text should be rotated by +30 degrees (vs the horizontal axis). In fact it points downwards by -30 degrees.
The problem does not appear under Ubuntu 22.04 (using libXft version 2.3.4), but it shows up on other Linux systems with newer version of libXft (and even on FreeBSD 13.1). In addition I compiled newer versions of libXft (up to 2.3.7) under Ubuntu 22.04 and used them with the demo program - all of them show the same problem.
