    Description:

         It activates a video mode via VESA driver. The advantage of using
         this driver is that you can forget about programming different SVGA
         cards as the VESA driver will make them all behave in the same way.

         The driver exists on most BBS < Universal VESA > that can be
         installed over a great number of chip sets. Nevertheless, It is
         recommended to use the specific VESA drivers for each card as these
         ones are more optimized.

    Return:

         The last video mode.

    Example:

         ? VESAMode( 257 )  // activate mi SVGA a 640x480x256 colors
