* spin_text()     - spinning wheel at the hercules screen. The given text   *
*                   must be a text constant, no variables or arrays. Its    *
*                   size is determined with the sizeof operator, it's much  *
*                   faster than the strlen function.                        *
* spin_text_vga() - same for vga.                                           *
