[Gnome-print] Where to put RGBA printing

[Lauris Kaplinski <lauris ariman ee>]

Hello,

RGBA printing with PS printers is mostly working for me. I implemented
that as separate context GnomePrintFRGBA, which can take any "real" 
context and emulate RGBA on that.

Now I am not sure, isn't separate context for RGBA simply overkill, as I
cannot imagine any other "real" context, needing ugly alpha emulating,
aside PostScript. So maybe it would be better to integrate that into PS
driver, and not pollute gnome-print object space more.

Suggestions?
