void textmode(int newmode);

   but i think this only sets text modes, maybe not graphics modes, although 
some of the following constants seem to be for colour graphics modes. Im' 
going by Borland docs for this, so a DOS compiler may have more graphics 
modes.

    /* DOS-compatible modes */

    LASTMODE = -1,
    BW40     = 0,
    C40,
    BW80,
    C80,
    MONO     = 7,
    C4350    = 64,

    /* New Color modes */

    C40X14   = 8,
    C40X21,
    C40X28,
    C40X43,
    C40X50,
    C40X60,

    C80X14,
    C80X21,
    C80X28,
    C80X43,
    C80X50,
    C80X60,

    /* New Black & White modes */

    BW40X14,
    BW40X21,
    BW40X28,
    BW40X43,
    BW40X50,
    BW40X60,

    BW80X14,
    BW80X21,
    BW80X28,
    BW80X43,
    BW80X50,
    BW80X60,

    /* New Monochrome modes */

    MONO14,             /* Invalid VGA mode */
    MONO21,
    MONO28,
    MONO43,
    MONO50,
    MONO60,

    _ORIGMODE = 65      /* original mode at program startup */

short setpixel(short x, short y);

   could be _setpixel. Sets pixel to current colour.

  You'll probably have to write this yourself, as display_image() isn't 
built-in either.

something polygon(int screen, int arraylen, int *xyarray, int colour);

I'm not sure about this one. I've only seen it in some code.

  The closest you can get is an array. You need to malloc() it and realloc() 
it when needed.
