Hi, Werner.

I'm not sure if this is the right place to reach you about this problem,
but I'm seeing some mysterious behavior in FreeType.

As part of the Android port, I'm writing a module to display TrueType
fonts.  This includes a TrueType interpreter for instructing fonts.

AFAIU, as long as a font does not perform an INSTCTRL which sets bit 2
in the instruction control, changes made to the graphics state from the
control value program will become the ``default'' state from which
glyphs are instructed.

However, some CJK fonts perform no INSTCTRL instructions at all, change
the projection vector and rp1 from prep, yet FreeType resets both to the
X axis and 0 respectively before any glyph programs are run.

Am I missing anything?  If not, could you tell me where this behavior is
documented?

Thanks.
