Simplify further thick lines
----------------------------
Key: GEOT-2781
URL:
http://jira.codehaus.org/browse/GEOT-2781 Project: GeoTools
Issue Type: Improvement
Components: core render
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 2.6-RC1
Thick lines are usually depicted with small artifacts when the actual lines has many tiny deviations over the main course. Take into account the line thickness when performing the generalization and generalize more thick lines. If we are depicting a line 6px wide we're not interested in changes of course that span only 1 or 2 pixels. Consider also using angles during the simplications (Jenks approach) by only using the derivative (dy/dx) to avoid using heavy trigonometric functions
