Firefox currently has a bug where resizeWidth/Height is not properly working and results in the image being squished or squashed. https://bugzilla.mozilla.org/show_bug.cgi?id=1733559 Therefore, compare canvas scaling to ImageBitmap scaling when it works (Chrome), and compared to just creating an ImageBitmap. Relevant: https://www.measurethat.net/Benchmarks/Show/5123/0/bug-with-resizing-imagebitmap-causes-slower-than-expect Setup can be visually inspected at: https://codesandbox.io/s/createimagebitmap-benchmark-setup-jldf3z?file=/src/index.js
