+Selections:
+ - moving in negative direction doesn't work
+ - selection state not properly reset, only works once
+ - selecting non-text objects is strange
+
+wxllist::GetSize() requires extra Layout() call, which should not be
+necessary. Find out why this is so.
+YES, it is necessary, because the normal drawing only happens within
+the visible window.
+I must find a way to re-Layout() objects. This is only required after
+their sizes change:
+- Just mark them as dirty:
+ - mark current line as dirty when editing it (so width gets recalculated)
+ - mark all following lines as dirty when changing font settings
+ - Let Layout() work only on the dirty lines.
+ !!! GOOD: this can also be used to recalculate the wxLayoutObjectCmds'
+ fonts! :-)
+
+- searching for text
+- moving cursor in non-edit mode
+- cursor screen positioning ignores font sizes once again :-(
+ --> UpdateCursorScreenPos() cannot work as it ignores previous font formatting commands.
+ Either draw cursor when drawing text, or wait for new wxLayoutObjectCmd to be fully
+ implemented.
+
+RECENTLY FIXED (?)
+ - fix(simplify) cursor size calculation
+ - delete in empty line doesn't work
+ - fix horiz scrollbar size OK here, a Mahogany problem?
+ - with a large number of lines, wraps to top of scrolled window
+ --> check where the problem lies, add a debug function showing all coordinates
+
+- update rectangle (needs support in wxllist and wxWindows)
+ --> needs a bit of fixing still
+ some code bits are commented out in wxlwindow.cpp
+ offset handling seems a bit dodgy, white shadow to top/left of cursor
