* Move gzipped size calculations into a worker and wrap it up in a `<GzipSize />` component that will also handle showing % of original size once that info is plumbed
* A couple tweaks for the app welcome (drop files) screen. We don't have mocks for this one, but this is at least a minor improvement.
* Prettier "pop" effect and styling for the drop zone/indicator.
* Styling for the quantization toggle to make it look like a disclosure triangle/button.
* Add controls bar (zoom in/out/to, background toggle). @todo: extract into its own component.
* When clicking/tapping the image area, give it focus.
* Utilities used by this PR
* Add a `two-up-handle` attribute to the handle for easier styling (classname gets mangled so it doesn't make for a good public API)
* Add a dummy comment to test netlify deploy
* Remove commented-out code.
* Fix styling of vertical split (which as it turns out is slightly different in the mocks anyway)
* Use a composited overlay for the dark background instead of animating background-color
* Move grayscale styling into `<two-up>` by default, then set colors via custom properties
* Remove commented-out svg fill
* Remove dummy comment
* Change `<GzipSize>` to be `<FileSize>`, add `compress` option that lets us show gzipped sizes later if we need. Defaults to `false`, and the gzip worker is only lazily instantiated the first time a compressed size calculation is requested.
* Dependency updates
* Remove color animations from dnd overlay
* Don't use a cyclical import for EncodedImage, instead just specify the types of the properties we Options actually uses.
* Pass source image through to FileSize component so it can compute delta
* Stylize size display with colors based on delta amount/direction
* Remove box-shadow animation.
* Simplify font stack
* Remove commented out code
* Remove gzip compression from size component
* Remove memoization bits
* Use specific flattend props instead of passing large context objects around.
* Remove unused packages.
* Remove unreachable String case in FileSize, and omit redundant File type
* Simplify calculateSize()
* Fix types for FileSize!
* Remove FileSize title
* Make delta variable consistent.
* Skip passing compareTo value for original image
* Remove manual focus
* Fix whitespace
* remove unused keyframes
* remove pointless flex-wrap property
* Remove unused resetZoom() method
* Remove pointless flex properties
* Use `on` prefix for event handling
* Remove pointless justify-self property
* Use an inline SVG for TwoUp's handle icon so it can be colored from outside the component..
* Move orientation state up from `<Output>` into `<App>` and share it with `<Options>`.
* Make the options panels responsive :)
* Show a plus sign for size increases `(+8%)`
* Use inline SVG for the zoom +/- icons, collect SVG icons into one file now that I've verified they get tree-shaken properly.
* Fix top/bottom options panels being reversed
* remove commented out code
* lockfile
* Revert quanitzation toggle styles so it's just a checkbox.
* Remove minimum delta for compare size
* Rename data prop to file.
* scale int -> float
* remove tabIndex
* Remove old icon files
* Add width to options panels
* Add vertical scrolling when options are taller than 80% of the screen height.
