-<H3>Description</H3>
- The <TT>Fl_Color_Chooser</TT> widget provides a standard RGB color
-chooser. You can place any number of these into a panel of your own
-design. This widget contains the hue box, value slider, and rgb input
-fields from the above diagram (it does not have the color chips or the
-Cancel or OK buttons). The callback is done every time the user
-changes the rgb value. It is not done if they move the hue control in
-a way that produces the <I>same</I> rgb value, such as when saturation
-or value is zero.

-Fl_Color_Chooser::Fl_Color_Chooser(int x, int y, int w, int h, const
-char *label = 0)</A></H4>
- Creates a new <TT>Fl_Color_Chooser</TT> widget using the given
-position, size, and label string. The recommended dimensions are
-200x95. The color is initialized to black.
-<H4><A name=Fl_Color_Chooser.~Fl_Color_Chooser>virtual
-Fl_Color_Chooser::~Fl_Color_Chooser()</A></H4>
- The destructor removes the color chooser and all of its controls.
-<H4><A name=Fl_Color_Chooser.hue>double Fl_Color_Chooser::hue() const</A>
-</H4>
- Return the current hue. 0 &lt;= hue &lt; 6. Zero is red, one is yellow,
-two is green, etc. <I>This value is convienent for the internal
-calculations - some other systems consider hue to run from zero to one,
-or from 0 to 360.</I>
-<H4><A name=Fl_Color_Chooser.saturation>double
-Fl_Color_Chooser::saturation() const</A></H4>
- Returns the saturation. 0 &lt;= saturation &lt;= 1.
-<H4><A name=Fl_Color_Chooser.value>double Fl_Color_Chooser::value()
-const</A></H4>
- Returns the value/brightness. 0 &lt;= value &lt;= 1.
-<H4><A name=Fl_Color_Chooser.r>double Fl_Color_Chooser::r() const</A></H4>
- Returns the current red value. 0 &lt;= r &lt;= 1.
-<H4><A name=Fl_Color_Chooser.g>double Fl_Color_Chooser::g() const</A></H4>
- Returns the current green value. 0 &lt;= g &lt;= 1.
-<H4><A name=Fl_Color_Chooser.b>double Fl_Color_Chooser::b() const</A></H4>
- Returns the current blue value. 0 &lt;= b &lt;= 1.
-<H4><A name=Fl_Color_Chooser.rgb>int Fl_Color_Chooser::rgb(double,
-double, double)</A></H4>
- Sets the current rgb color values. Does not do the callback. Does
-not clamp (but out of range values will produce psychedelic effects in
-the hue selector).
-<H4><A name=Fl_Color_Chooser.hsv>int
-Fl_Color_Chooser::hsv(double,double,double)</A></H4>
- Set the hsv values. The passed values are clamped (or for hue,
-modulus 6 is used) to get legal values. Does not do the callback.
-<H4><A name=Fl_Color_Chooser.hsv2rgb>static void
-Fl_Color_Chooser::hsv2rgb(double, double, double, double&amp;, double&amp;,
-double&amp;)</A></H4>
- This <I>static</I> method converts HSV colors to RGB colorspace.
-<H4><A name=Fl_Color_Chooser.rgb2hsv>static void
-Fl_Color_Chooser::rgb2hsv(double, double, double, double&amp;, double&amp;,
