[SDL] Pitch?

[Marc A. Lepage]

The example DrawPixel code has this for 16 bpp:

    bufp = (Uint16 *)screen->pixels + y*screen->pitch/2 + x;

Why pitch? What exactly is pitch? I have an idea but it's been awhile
since I did graphics.

Why can't you just use the w member?

    bufp = (Uint16 *)screen->pixels + y*screen->w + x;
