[birt-dev] Checkin: Fixed 3D chart bugs (white lines shown in Area, Tube

["David Michonneau" <dmichonneau@xxxxxxxxxxx>]

- Summary:

Fixed 3D chart bugs (white lines shown in Area, Tube and Cone charts)

- Bugzilla Bug (s) Resolved:

 

#184184, #165112

- Description:

Some complex 3D charts such as tube, cone and area use multiple polygons for drawing one datapoint representation (for instance one tube is made of several polygons). In that case, adjacent polygons seem to be separated by a white line, which is due to the antialiasing when each polygon is rasterized on the white background. To fix that issue, the engine will detect shared polygon edges, and draw behind them a small band of the same color so that the antialiasing uses the right background color.
