Followup to see if this I class is really needed?

Removed it. Think it was originally separate in case multiple Postscript
implementations existed for different OSes (CPSOutput contains an HDC member),
but since this is moving to the win32 folder and will be used for win only,
probably makes sense to just get rid of it. Let me know if you think it should
be added back.

Can we rename this file to cfx_psrenderer.h so it will have the correct name?

[rbpotter, 2017/01/05 22:58:18]

Done.
