GraphicStroke rendering poor due to missing antialiasing and interpolation
--------------------------------------------------------------------------
Key: GEOS-2486
URL: http://jira.codehaus.org/browse/GEOS-2486
Project: GeoServer
Issue Type: Bug
Affects Versions: 1.7.1
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 1.7.2
Using GraphicStroke shows many little artifacts due to missing antialiasing when painting the graphic elements. This is due to missing antialiaisng in the code that draws the mark and missing interpolation in the code that draws the image along the line (and that has to interpolate it properly to accomodate for the rotation).
