-// REMIND: Using an NSOpenGLPixelBuffer as the scratch surface has been
-// problematic thus far (seeing garbage and flickering when switching
-// between an NSView and the scratch surface), so the following enables
-// an alternate codepath that uses a hidden NSWindow/NSView as the scratch
-// surface, for the purposes of making a context current in certain
-// situations.  It appears that calling [NSOpenGLContext setView] too
-// frequently contributes to the bad behavior, so we should try to avoid
-// switching to the scratch surface whenever possible.
