Detailed Description

gfxFontShaper

This class implements text shaping (character to glyph mapping and glyph layout). There is a gfxFontShaper subclass for each text layout technology (uniscribe, core text, harfbuzz,....) we support.

The shaper is responsible for setting up glyph data in gfxTextRuns.

A generic, platform-independent shaper relies only on the standard gfxFont interface and can work with any concrete subclass of gfxFont.

Platform-specific implementations designed to interface to platform shaping APIs such as Uniscribe or CoreText may rely on features of a specific font subclass to access native font references (such as CTFont, HFONT, DWriteFont, etc).
