//         progress of downloading data, typically) because it has a large
//         number of factors (120 = 2*2*2*3*5).  This Win95 Progress Bar
//         control chops this width into "blocks" that it paints to
//         indicate progress.  We used to use 100 = 2*2*5*5, which didn't
//         have the factor 3, and so we were more likely to get the last
//         block chopped off.
