#12383: FillTrangle produces slightly different results if drawn in a BPicture

Description changed by jackburton:

Old description:

As shown by the FlattenPictureTest test, FillTriangle produces a slightly
different result when invoked inside a BPicture.
This happens because there is no FILL_TRIANGLE op in the BPicture
encoding, and it's handled using FillPolygon. Now, I'd expect that
FillPolygon(), when called with three points, would produce the same
output that FillTriangle does.

This happens because there is no FILL_TRIANGLE op in the BPicture
encoding, and FillTriangle is translated to a FillPolygon call. Now, I'd
expect that FillPolygon(), when called with three points, would produce
the same output that FillTriangle does.
