NanoGUI is a minimalistic cross-platform widget library for OpenGL 3.x and higher. It supports automatic layout generation, stateful C++ lambdas callbacks, a variety of useful widget types, and Retina-capable rendering on Apple devices. (Note: This port is for the {"old"} NanoGUI, which has been placed into maintenance-only mode by its author. However, most software projects that depend on NanoGUI as a library, are still using this version, instead of the newer version that has been re-written for the Mitsuba renderer. So even though this port is {"old",} it should not be considered to be deprecated or obselete.)
