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.
