   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

  19 Adding many lines makes it terribly slow.
  20 Printing produces empty pages only.
  21
  22 Formatting of first text in message in M is broken.
  23 Large images in last line don't get displayed properly.
  24 Taking last line's height as default for next is rubbish,
  25 use "default height" and adjust as necessary.
  26
  27 Selections:
  28   - moving in negative direction doesn't work
  29   - selection state not properly reset, only works once
  30   - selecting non-text objects is strange
  31
  32 wxllist::GetSize() requires extra Layout() call, which should not be
  33 necessary. Find out why this is so.
  34 YES, it is necessary, because the normal drawing only happens within
  35 the visible window.
  36 I must find a way to re-Layout() objects. This is only required after
  37 their sizes change:
  38 - Just mark them as dirty:
  39     - mark current line as dirty when editing it (so width gets recalculated)
  40     - mark all following lines as dirty when changing font settings
  41     - Let Layout() work only on the dirty lines.
  42   !!! GOOD: this can also be used to recalculate the wxLayoutObjectCmds'
  43             fonts! :-)
  44
  45 - searching for text
  46 - moving cursor in non-edit mode
  47 - cursor screen positioning ignores font sizes once again :-(
  48    --> UpdateCursorScreenPos() cannot work as it ignores previous font formatting commands.
  49        Either draw cursor when drawing text, or wait for new wxLayoutObjectCmd to be fully
  50        implemented.
  51
  52 RECENTLY FIXED (?)
  53   - fix(simplify) cursor size calculation
  54   - delete in empty line doesn't work
  55   - fix horiz scrollbar size OK here, a Mahogany problem?
  56   - with a large number of lines, wraps to top of scrolled window
  57     --> check where the problem lies, add a debug function showing all coordinates
  58
  59 - update rectangle (needs support in wxllist and wxWindows)
  60   --> needs a bit of fixing still
  61       some code bits are commented out in wxlwindow.cpp
  62       offset handling seems a bit dodgy, white shadow to top/left of cursor
  63
  64
  65   - replacement of llist in window
  66   - undo
  67   - font optimisations(!)
  68   - occasionally wraps lines wongly (twice) ??
  69   - UNDO
  70   later:
  71     - DragNDrop ... broken in wxGTK at present
  72     - cut&paste ... broken in wxGTK at present, Paste already implemented
  73     - Selections
  74
  75 - More optimisations:
  76   - let each line have a pointer to the last layoutcommand and let that
  77     one only store the settings that changed, then we no longer need to
  78     recalculate all the lines
