This changes some public API + that was broken in the 1.15 series. The new struct is backward compatible + with the older Pango series, but not with earlier 1.15.x devel releases. + +- New Public API: + + * PangoAnalysis.flags and PANGO_ANALYSIS_FLAGS_CENTERED_BASELINE. These are + mostly only useful for the vertical text support in Pango, but language + bindings probably want to update their bindings for PangoAnalysis to + include these. + + * New PangoMatrix methods: + + pango_matrix_transform_distance() + pango_matrix_transform_point() + pango_matrix_transform_rectangle() + pango_matrix_transform_pixel_rectangle() + + The transform_rectangle methods are particularly useful when an + app/toolkit wants to know the extents of a rotated layout in device + coordinates. It will be used by Gtk+ for example, and is used by the + pango-view tool too. The _pixel_ variant takes a PangoRectangle in device + units instead of Pango units. + + * Unit conversion helpers: + + pango_units_from_double() + pango_units_to_double() + pango_extents_to_pixels() + + The first two just convert between Pango units (fixed precision) and + double floating-point numbers. The current implementations are as simple + as "(int)floor (d * PANGO_SCALE + 0.5)" and "(double)i / PANGO_SCALE", but + the idea is to have optimized versions of these that do not use the FPU in + the future. That will be appreciated by embedded devices without FPU + units. Since the functionality can be generally useful, the API is made + public. + + The pango_extents_to_pixels() function in conjunction with + pango_matrix_transform_rectangle() makes it possible to convert extents to + device space and round then, instead of having to transform rounded + user-space extents. + +- Bugs fixed in this release: + Bug 351496 – PangoAnalysis::gravity breaks binary compatibility + Bug 388702 – Crash when there's no Hangul glyph in the font. + Bug 384543 – FcFontMatch misuse + Bug 392789 – vpath build fails in basic module + Patch from J.
