747849 - move small-caps support into gfx

Status: RESOLVED DUPLICATE of bug 1015603

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

Description

[John Daggett (:jtd)]

Small caps are currently synthesized using resizing code called from within layout text frame code:

http://mxr.mozilla.org/mozilla-central/source/layout/generic/nsTextRunTransformations.cpp#267

To properly support small-cap glyphs we need to detect whether a font supports small-cap glyphs and only do the synthesis if it doesn't support the OpenType 'smcp' feature.  This is a bit tricky since it essentially needs to happen after font matching is done.

What I'm proposing to do for this bug is to move the logic for doing small-caps synthesis down into gfx.  A later bug will implement the switch as to whether to use real small-caps or synthesize them.
