* Fixed issue-1011 by using single-point polygons for texts in deep mode. Tests need fixing.
* Updated tests (text become a single point)
* Added test for issue-1011
Sometimes, shapes from child cells were propagated into
parent cells in the L2N and LVSDB output.
Because of this fix, many testdata files have to be updated.
The problem was that with the floating test case, the
ambiguity resolution sometimes assigned the wrong pins
and floating pins/connected pins were swapped.
One option is to make the ambiguity resolver consider
the pin connection state when tenatively evaluating
nodes.
Another option is to put more emphasis on net names
and use them for ambiguity resolution. This has helped
here.
