OK cool... that's what I ended up doing, hoping a NULL would not burn me. :)

I also created a Xcode 2.2 version of the project by copying the 'Geom
Test' one.  Would you like it=3F

In any case, I have reproed the same bug that I see in our app!  On a
PPC Mac or in Rosetta I see a triangle with R G B corners.  On Intel I
see a blue triangle.  See attached picture (only 10kb, I hope the list
allows it).

So this is probably a Quesa bug.

One idea I have is this sentence here:

<http://developer.apple.com/documentation/MacOSX/Conceptual/
universal=5Fbinary/universal=5Fbinary=5Ftips/chapter=5F5=5Fsection=5F15.htm=
l>

"By default, NewGWorld always creates big-endian pixel formats
(k16BE555PixelFormat or k32ARGBPixelFormat), regardless of the endian
format of the system."

Maybe Quesa is incorrectly assuming that its gworlds have the same
endianess as the host system=3F

But that's just a guess...
