fix committed to rev 12420.
While testing the behaviour of the file stroke-to-path-regression-r12399.svg, it was found that there were a large number of redundant paths being generated, typically of a length of 0.0005 px. These were not present in the original code, before the grid was removed, and were clearly the result of numerical round-off error. Therefore the grid was re-introduced, but at a smaller spacing, just large enough to eliminate the redundant paths. The original grid spacing was 1/32 px. The new grid spacing is 1/512 px. This is large enough that the redundant paths do not appear, but is still sufficiently small that the errors reported in Bug 168158 are not observable.
With this new grid spacing, the file stroke-to-path-regression-r12399.svg behaves correctly on Windows XP.
