Fixes # #6525
Main PR
Description
When we serialize a GlyphRun to an XPS file, the advance widths for each glyph are rounded to an integer separately, thus producing a significant difference between the rendered output in the file and on the screen. This PR fixes the rounding, by taking into account the cumulative rounding error from the previous glyphs while rounding the current glyph.
