Description Kimmo Kinnunen 2021-12-08 04:21:46 PST 
GraphicsContextGLCocoa should signal forceContextLost immediately if prepareForDisplay fails to allocate next drawing buffer

Currently it expects to signal failure when makeContextCurrent fails when called with null drawing buffer

The makeContextCurrent is used universally to make the context current, also during initialisation when we do not yet have a drawing buffer.
