Some email just reminded me of two more wish items for R5.

Currently there is no way to allocate a shareable colormap cell only
if it already exists.  I would love to see an XGetAllocatedColor
function.  This function would fail if there was not already a
colormap cell with the given color value, even if there were free
colormap cells available.

I would also appreciate some way to convert read/write (private)
colormap cells to read-only (shareable) cells.  This way an
application can allocate as many colors as it can, set them to values
which won't be changed, make them shareable, then other applications
can share those colors.

These two functions are very desireable if your application needs to
allocate a lot of colors and wants to help keep technicolor effects to
a minimum.  Image processing and display programs fall into this
category.
