/*
23
 
 * Color space substitution at the library level is similar to, but not
24
 
 * identical to, the operation of UseCIEColor in the PostScript language.
25
 
 * When the Boolean UseCIEColor parameter of the current device is false,
26
 
 * everything operates as normal.  When UseCIEColor is true, the following
27
 
 * procedures may substitute another color space for the implied one:
28
 
 *
29
 
 *      gs_setgray, gs_setrgbcolor, gs_sethsbcolor, gs_setcmykcolor
30
 
 *      gs_current_Device{Gray,RGB,CMYK}_space
31
 
 *
32
 
 * Unlike the PostScript facility, the substitution *is* visible to
33
 
 * gs_currentcolorspace, and does *not* affect gs_setcolorspace, or the
34
 
 * ColorSpace members of images or shadings.  However, the following
35
 
 * procedures recognize when substitution has occurred and return the
36
 
 * value(s) appropriate for the pre-substitution space:
37
 
 *
38
 
 *      gs_currentgray, gs_currentrgbcolor, gs_currenthsbcolor,
39
 
 *        gs_currentcmykcolor
40
 
 *
41
 
 * Thus gs_{current,set}{gray,{rgb,hsb,cmyk}color} are always mutually
42
 
 * consistent, concealing any substitution, and gs_{current,set}{colorspace}
43
 
 * are mutually consistent, reflecting any substitution.
44
 
 * gs_{current,set}color are consistent with the other color accessors,
45
 
 * since color space substitution doesn't affect color values.
46
 
 *
47
 
 * As in PostScript, color space substitutions are not affected by
48
 
 * (ordinary) grestore or by setgstate.  Graphics states created by gsave or
49
 
 * gstate, or overwritten by currentgstate or copygstate, share
50
 
 * substitutions with the state from which they were copied.
