SVN commit 445236 by rchern:

- more flicker reduction: only draw simple solid shadows when drawing an object, and draw the real object when mouse button released
- cancel support for all drawing by hitting esc
- I think a 1 pixel wide blue border is enough for grouped objects (instead of 3 pixels)?
