Moving main curve implementation from GdipAddPathCurve2 to GdipAddPathCurve3, allow for use offset and nseg variables in GdipAddPathCurve3. The offset and nseg variables, will be used for fixing curve calculation in next commit. --- dlls/gdiplus/graphicspath.c | 89 ++++++++++++++++--------------------- 1 file changed, 38 insertions(+), 51 deletions(-)
