Writing a bit-mapped image to file using common windows.

[dunn@cs.psu.edu (Dennis F. Dunn)]

I am using X common windows under Allegro CL 3.1.4 on a Sun 4.
I create a bit-mapped image and then write it to a file.
Currently I'm using the command "window-stream-bit-xy" to read each pixel
but this is very slow (168x168 image takes about 45 min.).
There is an Xlib function "xgetimage" that should be faster. Is there a
way I can access this command through common windows?
