Add CMYK support for pens/fills in the PDF engine
Insofar, painting with a CMYK color (pen/brush) was completely ignored
by QPdfWriter, although the PDF format can faithfully represent CMYK
colors.
This commit adds support for CMYK colors in the PDF engine. The support
is opt-in, in the name of backwards compatibility; an enumeration on
QPdfWriter controls the output.
QPrinter was using a hidden hook in QPdfEngine in order to do grayscale
printing; this hook can now be made public API through the same
enumeration.
This work has been kindly sponsored by the QGIS project
(https://qgis.org/).
[ChangeLog][QtGui][QPdfWriter] QPdfWriter can now use CMYK colors
directly, without converting them into RGB colors.
