616281 - fix the wordwrap-02 reftest to be independent of platform fonts

Status: RESOLVED FIXED

(Core :: Layout: Text and Fonts, defect)

Description

[Jonathan Kew [:jfkthame]]

Attachment: patch, modify wordwrap-02 reftest to use in-tree font for portability

The reftest text/wordwrap-02, which is intended to test the shaping of Arabic script across line breaks, fails on most platforms because it requires the presence of a monospaced Arabic font, which is not usually available.

We can modify the test to use the DejaVuSansMono font that we have in the reftest/fonts directory, and thus allow it to work on all platforms regardless of the installed fonts.

To do this, we also need to change the reference file to use the pre-shaped "compatibility" Arabic characters at line edges, because DejaVuSansMono does not actually support the ZWJ character so we can't use that to "force" connecting forms.
