897938b8e4 Patch by Alexander Klenin 
- Extract duplicated code into TAGraph.LineInViewPort function.
- Heavily rearrange code inside TSerie.Draw and TAreaSeries.Draw procedures to enchance readability, remove code duplication and get rid of 'goto' statement.
- Fix a bug in TAreaSeries.Draw: areas higher then current viewport were not drawn.
- Use ACanvas parameter instead of ParentChart.Canvas in Draw procedures.
- Remove unused variables in TAGraph unit.
