Is there a way to make nemo-preview window bigger?

[chumariesco]

I use a retina display and the preview window of nemo-preview seems too small for me.

/usr/share/nemo-preview/js/ui/mainWindow.js

has a section on window scale factor I think, but I don't know how to increase it:
GLib.setenv("CLUTTER_SCALE", Math.max(s, 1).toString(), true);

Thank you wise people!

The minimal window size is configured in the constants.
For me the issue is with PDF files. I preview them to rename them but sometimes they are hard to read (dates). Increasing the window size does not increase the PDF view size so that's most likely a second issue.
