────────────────────────────────────────────────────────────────────────────
The _pg_initchart function initializes the presentation-graphics
package. It initializes the color and style pools, resets the
chartline style set, builds default palette modes, and reads the
font definition from the disk.
The _pg_initchart function is required in all programs that use
presentation graphics. This function must be called before any of
the other functions in the presentation-graphics library.
The _pg_initchart function assumes a valid graphics mode has been
established. Therefore, it must be called only after a successful
call to the C library function _setvideomode.
Return Value
The _pg_initchart function returns 0 if there were no errors. A
nonzero value indicates a failure.
