[feature]: more selection types (edgeless mode)

[UlyssesZh]

1~3 main use cases of the proposed feature

Sometimes I may want to have inclusive or exclusive selection of strokes in whiteboard mode. "Inclusive" means a stroke is selected as long as any part of it is in the selected area, and "exclusive" means a stroke is selected only when the whole of it is within the selected area. Introduce these four kinds of selections:

• Inclusive rect (already implemented);
• Exclusive rect;
• Inclusive lasso;
• Exclusive lasso.
