+This function converts a string to an immediate child widget of the parent
+widget passed as an argument. Note that this converter only works for
+child widgets that have already been created; there is no lazy evaluation.
+The string is first compared against the
+names of the normal and popup children, and if a match is found the
+corresponding child is returned. If no match is found, the string is
+compared against the classes of the normal and popup children, and if a
+match is found the corresponding child is returned. The case of the string
+is significant. To use this converter, include the following in your

+
+ <para>
+This function defines and retains as permanent resources all standard
+colormaps which are meaningful for the visuals of each screen of the
+display. It returns 0 on failure, non-zero on success. If the property of
+any standard colormap is already defined, this function will redefine it.

+
+ <para>
+This function is intended to be used by window managers or a special client
+at the start of a session.
+ </para>
+
+ <para>
+The standard colormaps of a screen are defined by properties associated with
+the screen's root window. The property names of standard colormaps are
+predefined, and each property name except
+<property>RGB_DEFAULT_MAP</property> may describe at
+most one colormap.
+ </para>
+
+ <para>
+The standard colormaps are: <property>RGB_BEST_MAP</property>,
+<property>RGB_RED_MAP</property>, <property>RGB_GREEN_MAP</property>,
+<property>RGB_BLUE_MAP</property>, <property>RGB_DEFAULT_MAP</property>,
+ and <property>RGB_GRAY_MAP</property>. Therefore a screen may
+have at most 6 standard colormap properties defined.
+ </para>
+
+ <para>
+A standard colormap is associated with a particular visual of the screen. A
+screen may have multiple visuals defined, including visuals of the same
+class at different depths. Note that a visual id might be repeated for more
+than one depth, so the visual id and the depth of a visual identify the
+visual. The characteristics of the visual will determine which standard
+colormaps are meaningful under that visual, and will determine how the
+standard colormap is defined. Because a standard colormap is associated
+with a specific visual, there must be a method of determining which visuals
+take precedence in defining standard colormaps.
+ </para>
+
+ <para>
+The method used here is: for the visual of greatest depth, define all
+standard colormaps meaningful to that visual class, according to this order
+of (descending) precedence:
+<symbol>DirectColor</symbol>;
+<symbol>PseudoColor</symbol>;
+<symbol>TrueColor</symbol>
+and
+<symbol>GrayScale</symbol>;
+and finally
+<symbol>StaticColor</symbol>
+and
+<symbol>StaticGray</symbol>.
+ </para>
+
+<para>This function allows success, on a per screen basis. For example, if a map
+on screen 1 fails, the maps on screen 0, created earlier, will remain.
+However, none on screen 1 will remain. If a map on screen 0 fails, none
+will remain.

+If replace is True, any previous definition of the property will be
+replaced. If retain is True, the property and the colormap will be made
+permanent for the duration of the server session. However, pre-existing
+property definitions which are not replaced cannot be made permanent by a
+call to this function; a request to retain resources pertains to newly
+created resources.

+This function returns 0 on failure, non-zero on success. A request to
+create a standard colormap upon a visual which cannot support such a map is
+considered a failure. An example of this would be requesting any standard
+colormap property on a monochrome visual, or, requesting an
+<property>RGB_BEST_MAP</property> on
+a display whose colormap size is 16.
