-/**
- * cgltf - a single-file glTF 2.0 parser written in C99.
- *
- * Version: 1.13
- *
- * Website: https://github.com/jkuhlmann/cgltf
- *
- * Distributed under the MIT License, see notice at the end of this file.
- *
- * Building:
- * Include this file where you need the struct and function
- * declarations. Have exactly one source file where you define
- * `CGLTF_IMPLEMENTATION` before including this file to get the
- * function definitions.
- *
- * Reference:
- * `cgltf_result cgltf_parse(const cgltf_options*, const void*,
- * cgltf_size, cgltf_data**)` parses both glTF and GLB data. If
- * this function returns `cgltf_result_success`, you have to call
- * `cgltf_free()` on the created `cgltf_data*` variable.
- * Note that contents of external files for buffers and images are not
- * automatically loaded. You'll need to read these files yourself using
- * URIs in the `cgltf_data` structure.
- *
- * `cgltf_options` is the struct passed to `cgltf_parse()` to control
- * parts of the parsing process. You can use it to force the file type
- * and provide memory allocation as well as file operation callbacks.
- * Should be zero-initialized to trigger default behavior.
- *
- * `cgltf_data` is the struct allocated and filled by `cgltf_parse()`.
- * It generally mirrors the glTF format as described by the spec (see
- * https://github.com/KhronosGroup/glTF/tree/master/specification/2.0).
- *
- * `void cgltf_free(cgltf_data*)` frees the allocated `cgltf_data`
- * variable.
- *
- * `cgltf_result cgltf_load_buffers(const cgltf_options*, cgltf_data*,
- * const char* gltf_path)` can be optionally called to open and read buffer
- * files using the `FILE*` APIs. The `gltf_path` argument is the path to
- * the original glTF file, which allows the parser to resolve the path to
- * buffer files.
- *
- * `cgltf_result cgltf_load_buffer_base64(const cgltf_options* options,
- * cgltf_size size, const char* base64, void** out_data)` decodes
- * base64-encoded data content. Used internally by `cgltf_load_buffers()`.
- * This is useful when decoding data URIs in images.
- *
- * `cgltf_result cgltf_parse_file(const cgltf_options* options, const
- * char* path, cgltf_data** out_data)` can be used to open the given
- * file using `FILE*` APIs and parse the data using `cgltf_parse()`.
- *
- * `cgltf_result cgltf_validate(cgltf_data*)` can be used to do additional
- * checks to make sure the parsed glTF data is valid.
- *
- * `cgltf_node_transform_local` converts the translation / rotation / scale properties of a node
- * into a mat4.
- *
- * `cgltf_node_transform_world` calls `cgltf_node_transform_local` on every ancestor in order
- * to compute the root-to-node transformation.
- *
- * `cgltf_accessor_unpack_floats` reads in the data from an accessor, applies sparse data (if any),
- * and converts them to floating point. Assumes that `cgltf_load_buffers` has already been called.
- * By passing null for the output pointer, users can find out how many floats are required in the
- * output buffer.
- *
- * `cgltf_accessor_unpack_indices` reads in the index data from an accessor. Assumes that
- * `cgltf_load_buffers` has already been called. By passing null for the output pointer, users can
- * find out how many indices are required in the output buffer. Returns 0 if the accessor is
- * sparse or if the output component size is less than the accessor's component size.
- *
- * `cgltf_num_components` is a tiny utility that tells you the dimensionality of
- * a certain accessor type. This can be used before `cgltf_accessor_unpack_floats` to help allocate
- * the necessary amount of memory. `cgltf_component_size` and `cgltf_calc_size` exist for
- * similar purposes.
- *
- * `cgltf_accessor_read_float` reads a certain element from a non-sparse accessor and converts it to
- * floating point, assuming that `cgltf_load_buffers` has already been called. The passed-in element
- * size is the number of floats in the output buffer, which should be in the range [1, 16]. Returns
- * false if the passed-in element_size is too small, or if the accessor is sparse.
- *
- * `cgltf_accessor_read_uint` is similar to its floating-point counterpart, but limited to reading
- * vector types and does not support matrix types. The passed-in element size is the number of uints
- * in the output buffer, which should be in the range [1, 4]. Returns false if the passed-in
- * element_size is too small, or if the accessor is sparse.
- *
- * `cgltf_accessor_read_index` is similar to its floating-point counterpart, but it returns size_t
- * and only works with single-component data types.
- *
- * `cgltf_copy_extras_json` allows users to retrieve the "extras" data that can be attached to many
- * glTF objects (which can be arbitrary JSON data). This is a legacy function, consider using
- * cgltf_extras::data directly instead. You can parse this data using your own JSON parser
- * or, if you've included the cgltf implementation using the integrated JSMN JSON parser.
