rgl is a 3D visualization system based on OpenGL. It provides a medium to high level interface for use in R, currently modelled on classic R graphics, with extensions to allow for interaction.
In an upcoming version of Rtools, there is one more dependency needed for freetype (brotli). This adds it to the linking. Also, the patch uses pkg-config, where available: this should allow some Rtools updates without followup updates in the package.
