QGAL (Test): redundant anchors shouldn't harm simplification
Adds a simple test to check whether redundant anchors avoid simplification to happen. In this case, the use of addCornerAnchors generate redundant anchors. Signed-off-by: Caio Marcelo de Oliveira Filho <caio.oliveira@openbossa.org> Reviewed-by: Eduardo M. Fleury <eduardo.fleury@openbossa.org>
