Re: XEmacs returns the wrong values for display-color-cells
Are there really 32-bit displays? I thought that those were all 24-bit displays
with 8-bits padding?
Would there really be any harm in claiming that a map with 4,294,967,296 cells
has "only" 16,777,216 for this purpose? Or EMACS_MAX_INT?
(Sorry for the top-post.)

What's happening is that it's returning the size of the default colormap,
not largest possible one.
I made it return a float to avoid overflow with a 32 bit depth display.
