* Implement basic refactorings
* Simplify some match statements
* Rename `ix` to `index`
If we're not going with a single letter name,
then a full word makes more sense.
* Rename `as_hex` to `to_hex`
`as_` implies lossless reinterpretation
while the function does a conversion that loses information
* Replace `for_each` with for loops
for loops are a lot easier to read and maintain.
* factor out x and y coords in Line::render
this is arguably more ergonomic
* Remove redundant `format!(format_args!())`
* 🎨 Add colors in Rust
* 🌿 Use an option for the properties and #[repr(C)]
* ❌ Remove WASM dependency on document.
* 😎 Wrap Fill and stroke in a style struct.
* 📦 Use crate::Color
* Merge Add transactions for temporary modifications to the document
* Run cargo fmt
* Color without a 'U'
