Integrate friendly tips from Tor colleagues to make (or not) 4.5 alpha 3;
This includes removal of overloaded (but unused) methods, and addition of
a overlooked call to DataStruct::SetData(nsISupports, uint32_t, bool.)

7 The size of the inner div is computed as follow:
9 Input:
10 outer_div_size: size of the div containing the scrollbar
11 button_size: size of the scrollbar arrow buttons
12 scrollbar_thickness: width/height of a vertical/horizontal scrollbar respectively
13 thumb_size: height/width of the thumb of a vertical/horizontal scrollbar respectively
14 Output:
15 inner_div_size: size of the div to be scrolled
17 Formula:
18 slider_size = outer_div_size - 2 * button_size - scrollbar_thickness
19 thumb_size = slider_size * (outer_div_size / inner_div_size)
20 which gives:
21 inner_div_size = (outer_div_size - 2 * button_size - scrollbar_thickness) * (outer_div_size / thumb_size)
23 Testcase constants:
24 outer_div_size = 200
26 On XP/Vista at 96 dpi with theme disabled:
27 thumb_size = 8 (minimum size)
28 button_size = 17
29 scrollbar_thickness = 17
31 inner_div_size = (200 - 2 * 17 - 17) * (200 / 8) = 3725
