Could you build this?
Partial Creating a cross-platform (macOS, iOS, Windows, Linux, Android) vector drawing app with infinite canvas rendering, low-latency stylus pressure support, and PDF multi-page annotation demands heavy graphics engineering.
What it would actually take: The implementation requires a high-performance graphics framework such as C++/Rust with Skia, or Flutter/WebAssembly using WebGL/WebGPU and CanvasKit. The complex components involve native stylus/Apple Pencil low-latency input sampling, spatial indexing (R-trees) for viewport culling on an infinite canvas, and embedded PDF vector parsing and rendering.
