This function supports everything from single lines up to and including the
unmodified contents of the whole `gamecontrollerdb.txt` file.
If you are compiling GLFW from source with CMake you can update the built-in mappings by
building the _update_mappings_ target. This runs the `GenerateMappings.cmake` CMake
script, which downloads `gamecontrollerdb.txt` and regenerates the `mappings.h` header
file.
Below is a description of the mapping format. Please keep in mind that __this
description is not authoritative__. The format is defined by the SDL and
SDL_GameControllerDB projects and their documentation and code takes precedence.
