The frames are on the Mac’s Finder window manager. 
I mean the PDF page as PNG image in a window of an Emacs frame.

The toolchain leaves [(DocView)] on the modeline and 
should be using the builtin Emacs infrastructure.

I’m after a variable that configures the width or page viewport size for next 
paging. Normally, I use buffer and indirect buffer for text to display at 
different text scale factors. I’m wanting that for PDF reading.
