* 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!())`
