 But your test case could shows problems with the AA + scaling. Mixing
 both has been known to be problematic in the past (i.e. the AA offset
 shouldn't be scaled but we don't control that).
 I'll add unit tests wrt [Draw|Fill][Rectangles|...] to ensure that,
 without scaling, our results match MS.

+New tests shows that we match MS behaviour for 1 and 3 pixels width
+but not for 2. That's probably an due to the precision when divising
+the pen's width (which differs from cairo and gdi+). It's likely that
+this occurs on most of the Draw* functions.
+However it doesn't create a blank (only an offset) between the draw
+and fill. Am almost convinced (and afraid) that this is AA+scaling
