Instead of testing the "windows" and "motif" styles, that test should
actually test the scrollBarRanges for all available styles. To be able
to do that, the magic numbers 16 (width/height of scrollbars) and 4
(spacing for the faux motif style) were replaced and instead of setting
the explicit values in the data the "number of scrollbars/spacings to
add/remove" is saved in a struct and the value of these (depending
on the style) is obtained in the test run.
This change does not also cause the fusion style to also be tested but
also fixes this test for Windows 7 and 8 (Aero) where the scrollbar
width/height is not 16 but 17.
