Hi,

I am making spirograph ( Epitrochoid/Hypotrochoid curves) drawing app. Paint derived from Examples/PainterExamples.

I have attached the project.

To draw spirograph with 12300 path points my routine take approximately 500 ms.

Want some suggestions to improve speed of draw.

I want to show animation like this
