test case
<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=770297">https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=770297</a> has a pdf that loses
the minus signs after running through pdftocairo.
I've reduced the pdf to a minimal test case that draws a single minus sign (the
minus sign is drawn as an image mask).
Reproduce with:
pdftocairo -pdf test.pdf out.pdf
or any other vector backend. The minus sign is lost.
eg
pdftocairo -ps test.pdf out.ps
and observe that the image is not included in the output:
%%EndPageSetup
q 0 883 0 1 rectclip q
Q Q
showpage
I found _cairo_pattern_get_extents was rounding the height down to 0. It seems
to be assuming that all backends are pixel based.</pre>
