327946 - Add font.name-list (font-set) support to Pango build

Status: RESOLVED WONTFIX

(Core :: Graphics, enhancement)

Description

[Jungshik Shin]

This is a follow-up to bug 288634 where most of additional 'features'/fixes added to nsFontMetricsXft were ported to nsFontMetricsPango. One conspicuous omission was 'font-set' support. Windows and Xft builds have supported  font.name-list.<generic>.<lang> for constructing a font-set. This is useful to those who hate less-than-pretty Latin, Greek, Cyrillic glyphs in non-Latin/Greek/Cyrillic fonts (e.g. CJK fonts). This feature is arguably critical for monospace (for some languages/scripts) because usually no high quality monospace font is available for them. For instance, with the following setting, the source code listing with occassional Korean strings would be a lot easier to view (note that UnDotum has variable-width ASCII glyphs while Korean glyphs are all monospace.)

font.name.monospace.ko = Bitstream Vera Sans Monospace
font.name-list.monospace.ko = UnDotum

This is obviously for 1.8.x branch given that Cairo will be used in 1.9/FF3.
I'm compiling FF with a patch. Will upload it once I'm done with testing.

Attachment: patch

This was made in February, but somehow I forgot to upload it. Need more testing.

Introducing a new feature like this on the 1.8 branch doesn't seem
worth the regression risk IMHO.

[Zack Weinberg (:zwol)]

I'm not sure if this is still a meaningful enhancement request.  Over to Core:Graphics for triage.

The 1.8 branch is no longer being developed.
