Well actually not: if you set the pageInc to 11 you get the thumb to 
jump 10 steps, but the markers see to be separated in steps of 8.3 (ie 
83 / 10)

To get tick marks like this (for the scale running from 0 -100):

    0    10    20    30    40    50    60    70    80    90   100

You need to set the pageInc to 12 ! And then of course clicking on the 
scroll bar jumps 11. Seems logical :)

Can someone confirm this with recent engines?
