the stuff from the sneak preview: For one, it still contains a few things that are already in CVS (the 'brown paperbag' changes). Secondly, this changes the ParagraphList to a std::vector but does not yet take full advantage of it except removing LyXText::parOffset() and similar. I had an extensive talk with my profiler and we are happy nevertheless. This also moves almost all Cut&Paste specific stuff from text.C to CutAndPaste.C. Much smaller interface now... Namespace CutAndPaste is now lyx::cap::. Was inconsistent with the rest.... Make ParagraphList a proper class. We'll need this later for a specialized erase/insert. Remove some unneeded prototypes and function declarations Use ParameterStruct directly instead of ShareContainer<ParameterStruct> Inline a few accesses to CursorSlice members as suggested by the profiler. Fix commandline conversion crash reported by Kayvan. Replace PosIterator by DocumentIterator. The latter can also iterate through math and nested text in math... Remove math specific hack from Documentiterator Derive InsetCollapsable from InsetText instead of using an InsetText member. This give us the opportunity to get rid of the InsetOld::owner_ backpointer. Cosmetics in CutAndPaste.C and cursor.C. Fix nasty crash (popping slices off an empty selection anchor). Add a few asserts. Remove all 'manual' update calls. We do now one per user interaction which is completely sufficient. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@8527 a592a061-630c-0410-9148-cb99ea01b6c8
