I know this might seem odd, but this is sort of working. The reason that this
is a purplish background is because we are actually blending the colours to
create the hatch. 

The hatch being used in the EMF is HatchStyle70Percent. According to the EMF+
specs, in actual fact this is "HatchStyle70Percent: Specifies a 70-percent
hatch, which is the ratio of foreground color to background color equal to
70:100."

Nevertheless, I wouldn't consider this fully fixed yet, because in fact we
haven't implemented any hatches other than the blending hatches. 

The code in question will need to be implemented in
EmfPlusHelperData::EMFPPlusFillPolygon(). The best way of implementing it would
be as a drawinglayer 2D primitive.
