I'm a new emacs user (spacemacs, really, switched from Vim), and I'm having difficulty configuring emacs on my HiDPI display. Basically, I'm suffering from this bug. The problem is that, while I can scale the font size on emacs fine, graphics and images don't scale. That's most apparent in inline images, say, in org mode, EIN, or anything that displays an image. Is there a way to just make all images twice as big, by default?
