+This was due to convertions from int32 to float (inside
+System.Drawing, no choice to satisfy both SD and GDI+ API) then from
+float to int32 (in libgdiplus). The later can overflow the integer
+(e.g. Int32.MaxValue) and result in a negative value (messing with
+measurements).
+
+Fixed in SVN r66589.
+Existing unit tests adapted to check this in r66591.
