Some more information here....

It seems I can't store colors into my colormap.  Or can't query them,
I'm not real sure.  Here is what's happening:

	mono_cmap = XCreateColormap(d, w, defaultvisual, AllocAll);
I get a valid map back.
Since I have AllocAll on, XAllocColorCells(...) fails, presumably this
is ok.  I used to do AllocNone and XAllocColorCells() would work, but according
to the source, it looked like this allocated read-only cells.
So, I no longer allocate color cells, I'm assuming that the AllocAll in
the XCreateColormap() does this for me.

I go on and:
	XStoreColor(d, mono_cmap, &def[i]);
256 times...after setting up def of course.  No failures here that I can see.
pixel 0 has red, green, and blue set to 255.
pixel 1 has red, green, and blue set to 0.

Then, I query pixel 0 and pixel 1:
	XQueryColor(d, mono_cmap, &def[0]);
	XQueryColor(d, mono_cmap, &def[1]);
The red, green, and blue values are zero!  (flags looks right though)


Q3:  What is going on?  Where is my mistake?
