示例2: DrawToTargetWithPathMask

        return;
    }
    enum {
        // the SW path renderer shares this stage with glyph
        // rendering (kGlyphMaskStage in GrTextContext)

    // We want to use device coords to compute the texture coordinates. We set our matrix to be
    // equal to the view matrix followed by a translation so that the top-left of the device bounds
    // maps to 0,0, and then a scaling matrix to normalized coords. We apply this matrix to the
    // vertex positions rather than local coords.
    SkMatrix maskMatrix;
    maskMatrix.setIDiv(texture->width(), texture->height());
    maskMatrix.preTranslate(SkIntToScalar(-rect.fLeft), SkIntToScalar(-rect.fTop));
