  Extracting directly from krono/highdpi-v2, fixes high-resolution scaling for both OpenGL and CoreGraphics backends. Note that the CoreGraphics backend is still kind of broken and should not be used on macOS 10.15.x or 11.x.x.

  For macOS platform, fixes drag-and-drop for high-resolution mode. Note that this change also makes the dragged file names/urls accessible directly after drag-enter, not just when letting go of the mouse button. Thus, the image can now show the dragged file names early on. The macOS dragging cursor is still visible though.

  For macOS platform, makes -core-graphics backend kind of usable again. There are still occasional segfaults that should be inspected. Also, the Smalltalk image must not rely on deferred updates in the VM but implement an extra composition buffer in the image. Squeak/Morph has #disableDeferredUpdates for this.

  For macOS platform, disable vsync for -metal backend to not slow down the VM interpreter loop.

NOTE THAT we now have sporadic segfaults as with the -core-graphics backend. There is a @synchronized missing somewhere. I suspect something around input events bc. the crashes always happen after a mouse click...

  -----------
  For macOS platform, fixes the sporadic segfaults...

...that started to happen after the recent changes to both -metal and -core-graphics backends, which entailed a slight change in what is actually in the view's event loop. That is, we added "redraw" events to work around vsync limitations. See uses of setNeedsDisplayInRect:.

The solution was, apparently, that we must not call the ancient Carbon-style pumpRunLoop() but always do the modern pumping via pumpRunLoopEventSendAndSignal().

Still, one of the remaining issues is that, for example, Squeak's #disableDeferredUpdates does not work for MVC-style display, which relies on the #copyBits side effect of directly pushing the contents to the screen. I will think of something such as pumping events from within the image.

  Merge remote-tracking branch 'origin/Cog' into krono/highdpi-v2

* origin/Cog:
  CogVM source as per VMMaker.oscog-mt.3177 [ci skip]
  CogVM source as per VMMaker.oscog-mt.3176 [ci skip]
  Newspeak source as per VMMaker.oscog-mt.3175 [ci skip]
  For macOS platform using -core-graphics backend, initialize colorMap32 like we do for all supported backends, even though we don't seem to accept display depths other than 32-bit (BGRA) these days, although we could because we the color-mapping tables (1-to-32, 2-to-32, etc.) still present.
  For macOS platform using -metal backend, do some code clean-up and add more commentary on where display events are generated to avoid slowing down the VM interpreter loop.
  For macOS platform, fixes the sporadic segfaults...
  For macOS platform, disable vsync for -metal backend to not slow down the VM interpreter loop.
  For macOS platform, disable vsync for -opengl backend to not slow down the VM interpreter loop.
  For macOS platform, makes -core-graphics backend kind of usable again. There are still occasional segfaults that should be inspected. Also, the Smalltalk image must not rely on deferred updates in the VM but implement an extra composition buffer in the image. Squeak/Morph has #disableDeferredUpdates for this.
  Fix typo in previous commit. :-/
  For macOS platform, explicitly allow "Open in low resolution" in case the default gets changed.
  For macOS platform, clean up code around mouse tracking. The flag NSTrackingInVisibleRect ensures that macOS will take care of resizing the tracking area when the window is resized.
  For macOS platform, fixes mouse tracking (entered, exited, moved), which got lost since macOS 10.5 where NSTrackingArea was introduced.
  For macOS platform, fixes drag-and-drop for high-resolution mode. Note that this change also makes the dragged file names/urls accessible directly after drag-enter, not just when letting go of the mouse button. Thus, the image can now show the dragged file names early on. The macOS dragging cursor is still visible though.
  Fixes initial screen refresh for macOS OpenGL backend when using high-resolution mode. Only applies to macOS 10.x.x because OpenGL support was dropped starting with macOS 11.x.x.
  Extracting directly from krono/highdpi-v2, fixes high-resolution scaling for both OpenGL and CoreGraphics backends. Note that the CoreGraphics backend is still kind of broken and should not be used on macOS 10.15.x or 11.x.x.
  For macOS platform, fixes high-resolution scaling when (1) reading prior display extent from image and (2) setting new extent via HostWindowPlugin.
  Extracting directly from krono/highdpi-v2, fixes high-resolution scaling for Metal backend.
  Command-line tools for Xcode have different SDK path
