>>TITLE XCopyColormapAndFree Xlib7
Colormap
XCopyColormapAndFree(display, colormap)
Display *display = Dsp;
Colormap colormap = DefaultColormap(display, DefaultScreen(display));
>>ASSERTION Good A
A call to xname creates a colourmap of the same visual type and for the same screen as the
.A colormap
argument and returns the new colourmap ID.
>>STRATEGY
For each supported visual:
   Create a colourmap using XCreateColormap with alloc set to AllocNone.
   Allocate one r/o cell, get it's actual rgb values
   Allocate the rest of the cmap as r/w and store known values, read them back.
   Create a new colourmap with XCopyColormapAndFree.
   Check that it contains the values we know we had in the original.
   Verify that no error occurred.

>>ASSERTION Good C
When the
.A colormap
argument
was created by the client with
.A alloc
set to
.S AllocAll ,
then all entries from the
argument
.A colormap
are moved to the new colourmap with the same colour values
and are freed
in 
.A colormap .
>>STRATEGY
For each supported visual class:
  Create a colormap with using XCreateColormap with alloc set to AllocAll.
  Fill with recognisable values.
  For each of the colour cells, record the rgb value with XQueryColors.
  Create a new colourmap with XCopyColormapAndFree.
  Verify that colourmap entries are identical with XQueryColors.
  Verify that all the previous cells in the original colormap are freed (i.e.
	that they can all be reallocated again).

>>ASSERTION Good C
If any of the visual classes
.S PseudoColor ,
.S GrayScale ,
or
.S DirectColor
are supported:
When the
.A colormap
argument
was created by the client with
.S AllocNone ,
then all of the entries from the
.A colormap
argument
that have been
allocated by the client using
.S XAllocColor ,
.S XAllocNamedColor ,
.S XAllocColorCells ,
or
.S XAllocColorPlanes
and not freed since they were allocated 
are moved to the new colourmap with the same colour values 
and the same read-only or writable characteristics and are freed
in 
.A colormap .
>>STRATEGY
For each of the visual classes DirectColor, PseudoColor and GrayScale:
  Create a colormap with XCreateColormap and AllocNone.
  Create a  new client with XOpenDisplay.
  Allocate two ro cells for First client with XAllocColor.
  Record their rgb values.
  Allocate two rw cells for First client with XAllocColorCells.
  Set their rgb values and record their rgb values.
  Allocate the rest of the colormap for Second client  with XAllocColorCells.
  First client copies the colormap and free owned cells with with XCopyColormapAndFree.
  Verify that the Second clients cells in copy are not allocated with XAllocColorCells.
  Verify that the First clients four cells in copy are still there with correct rgb values.
  Verify that the four allocated cells are freed, can be reallocated, in old cmap.
  Verify r/o and r/w behaviour of these 4 in copy, with XStoreColors.
