igl-nanovg

igl-nanovg is a project that combines nanovg with igl, enabling nanovg to run on opengl, metal, and vulkan.

Support Platforms : MacOS, Windows, Linux, iOS, Android.

The project originally wanted to submit a PR to merge into igl , but the Facebook/igl team thought that it conflicted with their principle of minimizing dependence on third-party projects, so i created this repository separately.

Original PR: facebook/igl#213
