Add Polar chart support...
Add Polar chart support This commit also heavily refactors things as polar chart needs separate implementation of various classes that previously only needed one, such as ChartAxis and ChartLayout. Task-number: QTRD-1757 Change-Id: I3d3db23920314987ceef3ae92879960b833b7136 Reviewed-by: Miikka Heikkinen <miikka.heikkinen@digia.com>
