CMYK support
InformationsAuthor: Fernando Herrero
License: GPL
DescriptionThis extension allows to use SetDrawColor(), SetFillColor() and SetTextColor() with Gray, RGB
or CMYK color spaces.
If you pass no parameter, you get black.
If you pass 1 parameter, it is a grayscale component (between 0 and 100).
If you pass 3 parameters, they are RGB components (between 0 and 255).
If you pass 4 parameters, they are CMYK components (between 0 and 100).

Description: Allow to use CMYK color space:
SetDrawColor() => Set draw color to black
SetDrawColor(int gray) => value in % (0 = black, 100 = white)
SetDrawColor(int red, int green, int blue) => 0 to 255
SetDrawColor(int cyan, int magenta, int yellow, int black) => values in % (0 to 100)
SetFillColor and SetTextColor same as SetDrawColor
