A simple justification algorithm is implemented + that tries to justify by expanding spaces in the line, and if none + found, by adjust letter spacing. [Based on patch by Mathias + Hasselmann] + +- The pango_script_get_sample_language() function is modified to use + the value of environment variables PANGO_LANGUAGE or LANGUAGE + (checked in that order) to make guess better languages for scripts. + The env var should be a list of language tags, like "en:fa" for + example where in effect makes Pango choose Persian (fa) fonts + instead of Arabic (ar) fonts when a run of text in the Arabic script + is found in an otherwise non-Arabic layout. + + This trick is also useful for East Asian languages. For example a + Japanese user that cannot set her primary language to Japanese can + still set PANGO_LANGUAGE="ja" and Pango will map CJK characters to + Japanese. + + The LANGUAGE env var is a standard gettext variable listing + languages the user wants to receive UI translated messages in. + However, since most packages don't provide separate English + translations, setting LANGUAGE="en:ja" doesn't have the intended + effect and UI messages will be shown in Japanese. For these + situations one can use LANGUAGE="en:C:ja". Pango skips the special + language tag 'C'. + +- Simplified embedded-shape rendering with pangocairo backends do. + [Richard Hult] + +- New header file: Moved PangoLanguage APIs into its own header + pango-language.h, which is included from pango-types.h. + +- ATSUI backend now lists synthesized italic faces like other + +- Misc optimizations and fixes. + +OpenType Layout Engine Improvements: + +- Vertical glyph variants are not selected in vertical text if the + font supports them. + +- Instead of hardcoded OpenType script tag in each module, and using + Default Language System unconditionally, Pango will now find and use + the script/lang-sys pair that best matches the detected script and + language of a run of text. Moreover, it also applies the OpenType + 'locl' feature. + + These, plus the PANGO_LANGUAGE env var, give font designers and + users lots of options to provide/choose language-specific glyph + variants. + + Only basic, arabic, and syriac modules updated to take advantage of + the new support so far. + +New pango-view command line options: + + --align + --justify + --language + +Public API Changes: + +- New public pangocairo API: + + PangoCairoShapeRendererFunc + pango_cairo_context_set_shape_renderer() + pango_cairo_context_get_shape_renderer() + + These are used by the default pangocairo renderer to render shape + attributes (see examples/cairoshape.c). Cairo-based PangoRenderer + implementations outside Pango may want to implement the draw_shape() + method similarly to provide compatibility with these new APIs. (See + bug #437533 for GdkPangoRenderer for example.) + +- Other public API changes: + + New is_expandable_space member in PangoLogAttr + New macro PANGO_UNITS_ROUND() + +- New OpenType engine API.
