// 'ttfCreate()' - Create a new font object for the named font family.
// 'ttfCreate()' - Create a new font object for the named font file.
//
// This function creates a new font object for the named TrueType or OpenType
// font file or collection. The "filename" argument specifies the name of the
// file to read.
//
// The "idx" argument specifies the font to load from a collection - the first
// font is number `0`. Once created, you can call the @link ttfGetNumFonts@
// function to determine whether the loaded font file is a collection with more
// than one font.
//
// The "err_cb" and "err_data" arguments specify a callback function and data
// pointer for receiving error messages. If `NULL`, errors are sent to the
// `stderr` file. The callback function receives the data pointer and a text
// message string, for example:
//
// ```
// void my_err_cb(void *err_data, const char *message)
// {
// fprintf(stderr, "ERROR: %s\n", message);
// }

// This function gets the bounds of all characters in a font. The "bounds"

// the limits for characters in the font scaled to a 1000x1000 unit square.

// This function computes the extents of a UTF-8 string when rendered using the
// specified font and size.
// This function computes the extents of the UTF-8 string "s" when rendered
// using the specified font "font" and size "size". The "extents" argument is
// a pointer to a `ttf_rect_t` structure that is filled with the extents of a
// simple rendering of the string with no kerning or rewriting applied. The
// values are scaled using the specified font size.
