/* Colour ConVerT: going from one colour space to another.
   ** NOTE: the set of available functions is far from complete! **

   Format descriptions:
   420i = "4:2:0 interlaced"
           YYYY UU YYYY UU   even lines
           YYYY VV YYYY VV   odd lines
           U/V data is subsampled by 2 both in horizontal 
           and vertical directions, and intermixed with the Y values.
   
   420p = "4:2:0 planar"
           YYYYYYYY      N lines
           UUUU          N/2 lines
           VVVV          N/2 lines
           U/V is again subsampled, but all the Ys, Us and Vs are placed
           together in separate buffers. The buffers may be placed in
           one piece of contiguous memory though, with Y buffer first,
           followed by U, followed by V.

   yuyv = "4:2:2 interlaced"
           YUYV YUYV YUYV ...   N lines
           The U/V data is subsampled by 2 in horizontal direction only.

   bgr24 = 3 bytes per pixel, in the order Blue Green Red (whoever came up
           with that idea...)
   rgb24 = 3 bytes per pixel, in the order Red Green Blue (which is sensible)
   rgb32 = 4 bytes per pixel, in the order Red Green Blue Alpha, with 
           Alpha really being a filler byte (0)
   bgr32 = last but not least, 4 bytes per pixel, in the order Blue Green Red
           Alpha, Alpha again a filler byte (0)
