   2 BUGS
   3 =====================================================================
   4
   5 - dmalloc shows duplicate deletion after merging two lines and
   6   deleting the second half
   7
   8 - word wrap for objects with lots of non-space needs to search in positive
   9   direction if begin of first object is reached
  10
  11   - delete in empty line doesn't always work
  12   - fix initial scrollbar sizes
  13   - fix horiz scrollbar size
  14

  16 TODO

  19 Selections:
  20   - moving in negative direction doesn't work
  21   - selection state not properly reset, only works once
  22   - selecting non-text objects is strange
  23
  24 wxllist::GetSize() requires extra Layout() call, which should not be
  25 necessary. Find out why this is so.
  26 YES, it is necessary, because the normal drawing only happens within
  27 the visible window.
  28 I must find a way to re-Layout() objects. This is only required after
  29 their sizes change:
  30 - Just mark them as dirty:
  31     - mark current line as dirty when editing it (so width gets recalculated)
  32     - mark all following lines as dirty when changing font settings
  33     - Let Layout() work only on the dirty lines.
  34   !!! GOOD: this can also be used to recalculate the wxLayoutObjectCmds'
  35             fonts! :-)
  36
  37 - searching for text
  38 - moving cursor in non-edit mode
  39 - cursor screen positioning ignores font sizes once again :-(
  40    --> UpdateCursorScreenPos() cannot work as it ignores previous font formatting commands.
  41        Either draw cursor when drawing text, or wait for new wxLayoutObjectCmd to be fully
  42        implemented.
  43
  44 RECENTLY FIXED (?)
  45   - fix(simplify) cursor size calculation
  46   - delete in empty line doesn't work
  47   - fix horiz scrollbar size OK here, a Mahogany problem?
  48   - with a large number of lines, wraps to top of scrolled window
  49     --> check where the problem lies, add a debug function showing all coordinates
  50
  51 - update rectangle (needs support in wxllist and wxWindows)
  52   --> needs a bit of fixing still
  53       some code bits are commented out in wxlwindow.cpp
  54       offset handling seems a bit dodgy, white shadow to top/left of cursor
  55
  56
  57   - replacement of llist in window
  58   - undo
  59   - font optimisations(!)
  60   - occasionally wraps lines wongly (twice) ??
  61   - UNDO
  62   later:
  63     - DragNDrop ... broken in wxGTK at present
  64     - cut&paste ... broken in wxGTK at present, Paste already implemented
  65     - Selections
  66
  67 - More optimisations:
  68   - let each line have a pointer to the last layoutcommand and let that
  69     one only store the settings that changed, then we no longer need to
  70     recalculate all the lines
