Package: libcairo2
Version: 1.10.2-6.2
Severity: normal
Attached very simple C program compiled and run as follows:
gcc -Wall `pkg-config --cflags --libs cairo` test.c -o test && \
./test && \
eog test.png
produces incorrect results in Debian testing with libcairo2 1.10.2 and
correct results in Debian stable with libcario2 version 1.8.10-6.
The output file generated by the test program (test.png) has two
lines of text. There should be one line of large text and one line
of small text. With libcario2 from testing, both lines are the
large size.

According to upstream, the problem was that I was using an X font (Terminus)
and that the for some reason (ie not a cairo problem) the font hinting was
working correctly.
In my application, I switched to 'Deja Sans Mono' font and everything
works again
