Affine Transforms — How Graphics Engines Move Everything

I was testing my vector engine and added a rotation.The curve disappeared — not off by a bit, completely gone, rendering at x=-649. Here's what was happening and how affine transforms fix it permanently. I finished building the Paths , Compound Paths , and even made some curve analysis method on the vector engine ( Arc Length , Curve-Curve Intersection , Path-Path Intersection etc.). Everything…
