To finish this thread: the manual pages say, no recently available X
server can serve a depth of 32 bits: 24 bits for colour + 8 bits for
transparency.
Xquartz:
-depth depth
Specifies the color bit depth to use. Currently only 15,
and 24
color bits per pixel are supported. If not specified,
defaults
to the depth of the main display.
XFree86:
-depth n
Sets the default color depth. Legal values are 1, 4,
8, 15,
16, and 24. Not all drivers support all values.
Xorg:
-depth n
Sets the default color depth. Legal values are 1, 4,
8, 15,
16, and 24. Not all drivers support all values.
XDarwin:
-depth depth
Specifies the color bit depth to use. Currently only 8,
15, and
24 color bits per pixel are supported. Ignored in
rootless
mode.
So with the existing means it's not possible to see transparency in
GNU Emacs on Mac OS X in X11.
With Xorg 7.1 I still have some problems. The most recent one is with
byte swapping. In Linux (my examples are from Fedora Core 5 for PPC)
there are the functions bswap{16,32,64}, as defined in /usr/include/
byteswap.h and /usr/include/bits/byteswap.h (effectively). Tiger has
something similiar in OSByteOrder.h: OSSwapConstInt{16,32,64},
OSSwapInt{16,32,64}, OSReadInt{16,32,64}, OSWriteInt{16,32,64}, ...
but for me it's not easy to understand which one can be a substitute.
The most simple solution would be to build an X server without GL
support!
