2121	Startup warning about Qt::AA_ShareOpenGLContexts	Tom Goddard	Tom Goddard	"ChimeraX on Mac is giving a startup warning

Attribute Qt::AA_ShareOpenGLContexts must be set before QCoreApplication is created.

This is a Qt bug, the warning comes from QWebEngine initialization as described in this Qt 5.12 bug report

	https://bugreports.qt.io/browse/QTBUG-76391

We also use a shared context when we go into sequential stereo so we should set this attribute and test that ChimeraX stereo is still working.
