1fa0a496bb Removed state from XrFiller that was redundant with state in XrPolygon. Fixed state update in XrStroker so that paths with multiple subpaths work. Simplified error-prone sorting in XrPenAddPoints. Renamed XrPenVertexTag to XrPenVertexFlag, (to allow for a single vertex that is the starting point for both the forward and reverse half-path). 2002-09-13 12:55:37 +00:00

2ba3786b27 Fixed rendering of degenerate splines. Changed XrStrokeFace to define everything in terms of the direction of the path 2002-09-10 09:51:14 +00:00

5f1938f26f Fixed spline error calculation. New effort to compute spline initial/final slopes even for degenerate splines, (degenerate splines are still broken somewhere though). 2002-09-10 08:01:00 +00:00
Carl Worth
44ca388c90 Fix polygon stroking so last final face is rendered exactly. Fix bug in which XrPolygonAddPt with horizontal edge would then drop the next edge. 2002-09-05 13:12:23 +00:00

13216da122 Fixed pen to transform user-space radius to device space, (vertices_needed computation still broken). Pen now behaves well when an extra point is coincident with an original vertex point. 2002-09-04 07:28:56 +00:00
