/*
 * The generic Tk code uses the X11 GC type to describe a graphics context.
 * (A GC is a pointer to a struct XGCValues).  The foreground and background
 * colors in a GC are unsigned longs.  These are meant to be used as indexes
 * into a table of XColors, where an XColor is declared in Xlib.h as:
 * typedef struct {
 *       unsigned long pixel; 
 *       unsigned short red, green, blue;
 *       char flags;
 *       char pad;
 * } XColor;
 *
 * The xlib function XParseColor creates XColors from strings.  It recognizes
 * literal hexadecimal color specifications such as "#RRGGBB" as well as the
 * standard X11 color names.  When XParseColor creates an XColor it fills in
 * all of the fields except for the pixel field, and then passes the XColor
 * to TkpGetPixel to get a value to use for the pixel field. Since TkpGetPixel
 * is platform specific, each platform is free to choose a value which can
 * be used to set the foreground or background color in the platform's graphics
 * context.
 *
 * Tk represents a color by a struct TkColor, which extends the XColor struct.
 * Tk provides a mapping from color names to TkColors which extends the mapping
 * provided by XParseColor but also allows for platform specific color names.
 * By convention, these platform specific color names begin with the string
 * "system".  The mapping from names to TkColors is implemented by the function
 * TkpGetColor defined for the Macintosh in this file.  The pixel field in the
 * XColor contained in a TkColor will be stored in the X11 graphics context.
 * In X11 the pixel field is used as an index into a colormap.  On the Mac
 * the high order byte of the pixel is used to indicate a color type and
 * the low 24 bits are either used as an rgb value (if the type is rgbColor)
 * or as an index into a table of color descriptions.
