CoreGraphicsCanvas

class CoreGraphicsCanvas(ctx: <Error class: unknown class>)

PdfCanvas backed by an iOS / macOS CGContextRef. Pure CoreGraphics — no Compose, no Skia. The natural choice for native iOS apps using UIKit or SwiftUI; pass the context from your custom UIView's drawRect: or the UIGraphicsImageRenderer.image { ctx in … } block straight in.

Pair with ApplePdfRasterizer for the "give me a PNG" headless use case.

Memory: every Core Foundation / Core Graphics ref we allocate (gradient, colour space, image, CFData) is paired with a release call. Nothing escapes — Kotlin/Native objects don't leak, and we never hand a CG ref to caller code.
