Ah, that would change the whole system – I want a VM that uses "high-DPI"
mode.

Actually now I remember that Tobias Pape built one a while ago. Lo and
behold, it works:

On top is the latest Cuis VM from dropbox.

Below is a VM with high dpi enabled. You can easily see that the VM below
uses full retina resolution, whereas the standard VM duplicates pixels by a
factor of 2, making everything blurry.

Of course that VM does not have the Vector plugin so everything is very
very slow. But gorgeous 😍

So ... this is the experimental VM:
https://github.com/OpenSmalltalk/opensmalltalk-vm/files/2999560/Squeak64_201706232142-highdpi-v2.app.zip

Try it if you have a Retina Mac! Smalltalk never looked so good before! 💜

This is the ticket where I found that VM:
https://github.com/OpenSmalltalk/opensmalltalk-vm/issues/378

... but it was closed because it was deemed "too hard to get right" 😟

Maybe someone could take another run at the fence? All the vector graphics
gorgeousness only really comes out at full resolution. Or maybe there has
been some vm development I don't know about?
