>>ASSERTION Good A
A call to xname
removes the association between the

argument
and the colourmap ID, and frees the associated storage.
>>STRATEGY
For each supported visual type:
Create a colourmap with XCreateColormap.
Free the colourmap with XFreeColormap.
Verify that XAllocColor fails.

>>ASSERTION Good A
When the
.A colormap
argument is the default colourmap, then a call to xname
does not remove the association between the
.A colormap
argument
and the colourmap ID or free the associated storage.
>>STRATEGY
Free the default colourmap with XFreeColormap.
Verify that XAllocColor succeeds in allocating 1 shared cell with this colormap.

>>ASSERTION Good A
When the
.A colormap
argument is an installed colourmap, then a call to xname uninstalls the colourmap.
>>STRATEGY
For each visual class:
Create a colourmap with XCreateColormap.
Install the colourmap with XInstallColormap.
Obtain a list of installed colourmaps with XListInstalledColormaps.
Verify that the created colourmap is in the list.
Free the colourmap with XFreeColormap.
Obtain a list of installed colourmaps with XListInstalledColormaps.
Verify that the created colourmap is not in the list.

>>ASSERTION Good A
When the specified colourmap is defined as the colourmap for a window,
then a call to xname changes the colourmap associated with the window to
.S None
and generates a
.S ColormapNotify
event.
>>STRATEGY
For each supported visual class:
Create a colourmap with XCreateColormap.
Create a window with XCreateWindow.
Select ColormapNotify events with XSelectInput.
Make the colormap the colormap for the window with XSetWindowColormap.
Free the colormap with XFreeColormap
Verify that a ColorMapnotify event was generated with XNextEvent.
Verify that the window's colourmap is set to none with XGetWindowAttributes.
