femtovg
GPU Antialiased 2D vector drawing library written in Rust.
Ported from https://github.com/memononen/nanovg
Most of the implementation is the same as the original C code with some bug fixes, some features added and several parts have been made more Rust-y. Rendering is done via one OpenGl (ES) 3.0+ backend.
