[TODO]

Following operators support logical expressions of canvas tags (for Tk8.3+). If tag1.path is 't1' and tag2.path is 't2', then

ltag = tag1 & tag2; ltag.path => "(t1)&&(t2)"
ltag = tag1 | tag2; ltag.path => "(t1)||(t2)"
ltag = tag1 ^ tag2; ltag.path => "(t1)^(t2)"
ltag = - tag1;      ltag.path => "!(t1)"
