 you come to the value 3.  Since we are using
 26.6 fractional numbers for vectors, there are
 actually 64
 possible fractional offsets.

Just the typical intended usage - LCD's with 3 elements. Just shifting
without horizontal hinting would cause a lot of colour fringes for every 
vertical stem.

Horizontal hinting would also ikely reset and nullify the fractional advance... 
definitely a lot to think about.

BTW, I rewrote and enhanced one the freetype-py sample to do also LCD_V in 
cairo - here is the drawing:
