#380 Use a specific font in tests

[Petr Písař]

In Fedora we saw that tests are sensitive to fonts installed into a system and sometimes fail because of that. Thus we apply an attached patch. It requests a convert command of ImageMagick to use a known font family. That makes the test more reproducible. Please consider merging the patch. Feel free to choose a different font if DejaVu Sans is not good enough for you.

I saw this on Debian, too and reported it as a bug in Imagemagick, which I think should always have sensible defaults for fonts.

imagemagick upstream suggested this fix:

https://bugs.debian.org/cgi-bin/bugreport.cgi?att=0;bug=980202;msg=65

I switched to graphicsmagick (in the Debian packaging) for the tests in question to get them to pass.

But your patch implements imagemagick upstream's alternative suggestion, so I'll commit it.

Thanks!

I noticed that I added a typo into t/431_gocr.t. A new fix is attached.

Committed, thanks!
