Retina displays not supported

[behdad]

High-DIP (i.e. Macbook Retina Pro) still draws at standard resolution.

Why is that the case?

Hi! Is there any way to make it run in Retina?

It looks like the GLUT framework shipped with macOS doesn't have support for HiDPI, so to get something like that working you'd have to find a way to get the native NSWindow and then the NSOpenGLView to toggle on the desire for HiDPI. Additionally, something would need to call the reshape func with the scale factor applied.
