The big issue is redrawing just the part that has changed. It would be
nice to wireframe or highlight the current piece as well, but the speed
thing is for LDLite to discover (or be told) which part of the file
needs redrawing.
Actually, more than one piece may be 'current' in LDAO, because you
select a range of pieces. So indicating the current piece(s) may
require drawing a number of parts in a special way (wireframing,
dithered edges, whatever).
