The handler accumulated every rect from one EmfPlusFillRects
record into a single B2DPolyPolygon and emitted a single
PolyPolygonColorPrimitive2D, which drawinglayer fills under the
even-odd rule. With overlapping rects, even-odd cancels pairwise
overlaps - three south-east-shifted gray squares rendered as
filled-then-hollow-then-filled stripes (the triple-overlap centre
came back as filled because three crossings is again odd).
Per MS-EMFPLUS each rect in EmfPlusFillRects fills its interior
independently; there is no fill-rule choice. Emit one fill
primitive per rect inside the loop and keep the polypolygon path
only for EmfPlusDrawRects, where stroking is independent of fill
rule so the existing single-call shape stays correct.
Tests: testEmfPlusFillRectsOverlap with three 300x300 squares
shifted south-east by 100px each (extracted from the tdf#107034
sample EMF) asserts three separate polypolygoncolor primitives
rather than one combined.
