Add new paragraph justification option "Maximum letter spacing" to distribute letters on (part of) the available blank area of the justified line instead of overstretching word spacing, like DTP software do. This improves typography a lot, allowing typesetting visually better i.e. more readable paragraphs, minimizing or removing rivers and too big word spacing (which was common in columns or text without hyphenation). * Add spin box to Alignment in paragraph formatting dialog window, (also add spin boxes for future Minimum and the alternative percent-based Desired letter spacing, see CharKerning); For example (only ASCII visualization!), 100% maximum letter spacing adds a space character-width blank space between the characters, including the original space: 0%: Lorem ipsum pellentesque dolores vitae. 100%: L o r e m i p s u m pellentesque dolores vitae. Normal value: 3%-5% (or more for very narrow columns), which means e.g. 1-2 twips (twip = 1/20 pt) letter spacing in a ~12 pt text. Note: resolution of the custom letter spacing is only 1 twip yet. * Store properties in paragraph model: css::style::ParagraphProperties::ParaPropLetterSpacingMaximum css::style::ParagraphProperties::ParaPropLetterSpacingMinimum Note: desired letter spacing is already supported by ODF/UNO, see css::style::CharacterProperties::CharKerning. * Implement visual layout of maximum letter spacing. Note: after the last character of the line, there is an unwanted letter-spacing, yet (which is visible only with big letter-spacing values). * Add ODF import/export (loext:letter-spacing-maximum and loext:letter-spacing-minimum) * Add ODF unit test. Note: hyphenated lines and lines with multiple portions do not yet use custom letter spacing, yet.

LibreOffice API IDL Files Except UDK API
Contains all of the IDL files except those in udkapi.
i.e. the interfaces that are specific to the LibreOffice application. An artificial (?) separation.
The reference offapi/type_reference/offapi.idl and
udkapi/type_reference/udkapi.idl (formerly combined into a single
offapi/type_reference/types.rdb) are used to detect inadvertent incompatible
changes. They are plain-text .idl files (not strictly lexicographically sorted,
though, so they satisfy the .idl file requirements for no forward dependencies),
so in cases where we deliberately /do/ become incompatible they can be modified
manually.
Old such cases of deliberately becoming incompatible are listed in
offapi/type_reference/typelibrary_history.txt, newer such cases are recorded in
the git logs of (now superseded) offapi/type_reference/types.rdb,
offapi/type_reference/offapi.rdb, and udkapi/type_reference/udkapi.rdb, new such
cases are recorded in the git logs of offapi/type_reference/offapi.idl and
udkapi/type_reference/udkapi.idl.
