Add TinyGL (https://github.com/C-Chads/tinygl), a small software-only implementation of a subset of OpenGL 1.1 written in portable C99, by Fabrice Bellard, Gek and C-Chads, under a zlib-style license. Like graphics/lvgl, the sources are not kept in the repository: the build downloads a pinned git revision from GitHub (CONFIG_TINYGL_VERSION) and applies the NuttX patches that live next to the Makefile: 0001 zfeatures: allow overriding the feature switches at build time 0002 Fix -Wstrict-prototypes warnings 0003 zbuffer: do not over-read the source in ZB_copyFrameBuffer() 0004 zbuffer.h: make the default allocator wrappers static inline The TinyGL compile time features (pixel depth, GL_SELECT, GL_POLYGON, blending, texture size, ...) are exposed as CONFIG_TINYGL_* Kconfig options. They change public structures, so Make.defs / CMakeLists.txt export them to every application that includes <GL/gl.h> or <zbuffer.h>. Both the make and the CMake builds are supported. An unpack stamp file makes sure an object directory created inside the source tree is never mistaken for downloaded sources.
