    a viewport range of tiles above and below and then
    scrolling feels smooth

  • Continued working on Presentation view separation
    • This unearthed a different bug that I switched my attention to that is
      most likely related and had to be addressed first
    • Opening a document, then opening the same document from a different
      client gives the second client a (canonical) view id of 1000. This is wrong.
      View ids of 1000 shouldn’t exist as view ids are 1000 + size of clients. The
      only reason a view id of 1000 exists is because it hasn’t yet received the
      callback that sets its view id. And the reason for that was that internally
      EditableConfig is using a static variable and there’s a check in
      .uno:ChangeTheme where it doesn’t change the theme if the theme name is the
      same. So no theme name change, so no kit callback, so no view id
      invalidation. Should be fixed after my patch is pushed, shouldn’t get view
      ids of 1000 anymore.
  • Fixed bug where on dark mode scrolling up and down would leave behind
    white color due to the background behind the tiles being hardcoded to white,
    now is the actual document color.

Add basic interoperable document theming to Calc & Writer

  • OOXML Theme color round-trip for cell text color, background color and
    border color
  • Works now, but kind-of messy because Calc OOXML export is messy
  • Theme export (theme1.xml) in Calc
  • need to work on putting the theme info at a proper place - currently
    always to the first SdrPage
  • probably best to add into SdrModel (also for Writer)
  • Started with undo/redo support and char level text color support (editeng
    level - not per cell)
