Bugzilla #49403:
Initial support for PDF Separation color spaces (aka spot colors). This is still unfinished but produces valid PDF with Separation colors in simple cases.
Based on work by: Patrick Jaromin <Patrick.at.Jaromin.com>

Note: PDFColor is broken right now, as I'm planning to phase that class out. Squeezing separation colors and what else comes later into that class isn't such a good idea IMO. Instead, PDFColorHandler tries to do all that in a better way based on the new color support classes from XGC.
