Class SharedSubsetScrollAxis

SharedSubsetScrollAxis implements scrolling logic for both horizontal and vertical scrolling in a ScrollAxisControl that is embeded in a parent scroll axis control.

Logical units in the ScrollAxisBase are called "Lines". With the ScrollRows a line representes rows in a grid and with ScrollRows a line represents columns in a grid.

SharedSubsetScrollAxis supports pixel scrolling and calculates the total height or width of all lines.
