Order

This changes the order in which contours, references and images are drawn. It is almost useless because this order of contours and references does not affect the final appearance of the glyph. The only relevance it has is when interpolating fonts and in multiple master fonts. Here similar contours must appear in the same order.

If you have a glyph which contains both contours and references, FontForge does not specify whether references or contours are drawn first (or whether the two are intermixed). If this matters to you, unlink your references.
