// ppvecstr - Definition of rendering PathProcessor classes for Vector Path Stroking

/********************************************************************************************

>   class PathProcessorStrokeVector : public PathProcessorStroke

    Author:     Jason_Williams (Xara Group Ltd) <camelotdev@xara.com>
    Created:    18/2/97

    Purpose:    A path processor which "moulds" vector clipart along a path.

                These classes are created by attributes (or similar) when rendered,
                and placed on a stack in the RenderRegion. Whenever RenderRegion::DrawPath
                is invoked to render a path, all stacked PathProcessors will be called in
                turn, and they call back to RenderRegion functions to render whatever they
                wish (usually a modified form of the original path).

                This can be used to "filter" almost any rendering, but is mainly intended
                for use by stroke and fill providers, which replace input paths with more
                suitable shapes to be rendered.

    Notes:      This processor is set up with a vector clipart "group" which it "moulds"
                along each stroke it renders in ProcessPath.

    SeeAlso:    RenderRegion::DrawPath; PathProcessor::ProcessPath;
                StrokeDefinition; StrokeComponent
