macOS: Make retina OpenGL work on VMware
Qt requests full resolution OpenGL surfaces by default.
However, when running as a VMware guest it looks like
the OS silently creates low-resolution surfaces.
This is not possible to detect using the standard NSWindow
APIs for converting to backing coordinates or for
reading the backing scale factor. The result of this
is that Qt will incorrectly display one quarter of
the window content only.
Fall back to detecting if the OpenGL renderer is the
Apple software renderer, which it will be on VMware.
Cancel the high-resolution surface request if this
is the case. This needs to be done while we have a
valid OpenGL context.
Task-number: QTBUG-62357
