      ;Note 2:multiplying by CZ accounts for the difference in reported canvas size that occurs when not at 1.0 zoom
      ;Previous implementations set zoom to 1.0 before changing canvas dimensions.
      ;This could would cause distortions when changing between canvases of different sizes and not at 1.0 zoom
