notodiff: png image is not wide enough

[marekjez86]

I'm not sure how we decide on how wide the diffed image should be.
Here's the input (left --before; right --after)

the diff image is missing significant information (IMHO)

What font is this?

[marekjez86]

This was from diff of
--before https://github.com/googlei18n/noto-fonts/blob/master/alpha/from-pipeline/NotoSansJavanese-Regular.ttf
and
--after (look for submission in notofonts/noto-fonts#792 )

[jamesgk]

Which glyph's image did you attach? I don't see any notodiff output quite like that.

[marekjez86]

--before NotoSansJavanese-Regular.ttf.zip
--after NotoSansJavanese-Regular-c.ttf.zip

look for jv__d_dha__pas

[jamesgk]

Huh, when I run notodiff on those two fonts I get
Mark class mismatch for jv_Ddha_pas (no class vs mark)
and no jv__d_dha__pas.png is generated.

I should have a fix soon for rendering widths anyways, but it's strange that we'd see different things here.
