OK, so all new patch. It should apply to emacs-26 without any
additional patches (and might be OK for master too). Just the usual
’git am’ should apply all four, I believe.

If you can ignore the outer border randomly drawing in the wrong
colour, images being upside down and live‐resize displaying the frame
in black, then you’ll probably get along pretty well with this.

(There’s also a slightly odd redrawing issue with the title and tool
bars when dragging between monitors. No idea why that’s happening.)

Additionally, the fonts are drawn differently. I imagine that’s the
lack of subpixel anti‐aliasing that Yamamoto Mitsuharu talks about in
the Mac port release notes, in which case you won’t notice anything on
10.14.
