The goal is to have both good metrics computation (and -font with proper kerning and ligatures) and better performance than -what we have with force_paint_single_char. Moreover there has been -some code factorization in TextMetrics, where the same row-breaking -algorithm was basically implemented 3 times. - -The bugs fixed and caused by this branch are tracked at ticket #9003: -http://www.lyx.org/trac/ticket/9003 - - -What is done: - -* Make TextMetrics methods operate on Row objects: breakRow and - setRowHeight instead of rowBreakPoint and rowHeight. - -* Change breakRow operation to operate at strings level to compute - metrics The list of elements is stored in the row object in visual - ordering, not logical. This will eventually allow to get rid of the - Bidi class. - -* rename getColumnNearX to getPosNearX (and change code accordingly). - It does not make sense to return a position relative to the start of - row, since nobody needs this. - -* Re-implement cursorX and getPosNearX using row elements. - -* Get rid of lyxrc.force_paint_single_char. This was a workaround that - is not necessary anymore. - -* Implement proper string metrics computation (with cache). Remove - useless workarounds which disable kerning and ligatures. - -* Draw also RtL text string-wise. This speeds-up drawing. - -* Do not cut strings at selection boundary in RowPainter. This avoids - ligature/kerning breaking in latin text, and bad rendering problems - in Arabic. - -* Remove homebrew Arabic and Hebrew support from Encoding.cpp. We now - rely on Qt to do handle complex scripts. - -* Get rid of LyXRC::rtl_support, which does not have a real use case. - -* Fix display of [] and {} delimiters in Arabic scripts. -- 2.39.5
