'Display' just redraws already rendered layers composition.
'Re-render' renders all layers and creates new layer composition which
is afterwards displayed in the map canvas (e.g. when you zoom, add new
map layer, etc.) BTW you can enable auto-rendering in the statusbar of
map display window. Then content of map canvas is automatically
re-render on every event (adding new layer, changing layer properties,
