You are probably misunderstanding.  *Of course* Microsoft and Apple
support colour bitmap fonts (or rather, bitmap strikes).  The question
is how those platforms behave for glyph IDs without a bitmap.  I
suppose they do as Behdad suggest, this is, returning an empty bitmap
with the given advance width (or height).
