// '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);
