Detailed Description

FreeTypeFontEnginePlugin is the FreeType font engine plugin implementation.

Font engine plugins contain both font loaders for creating FontFile objects and shapers. Kanzi uses the shapers to shape text that uses Fonts from the same plugin.

FreeTypeFontEnginePlugin uses FreeType for rasterizing fonts, Harfbuzz for shaping, ICU bidirectional algorithm and libunibreak for line breaking.
