The **most notable difference** between the C API and the Zig bindings is that opening and closing the scope for declaring child elements must be done "manually" using 2 function calls.

other differences include:
- minor naming changes
- ability to initialize a parameter by calling a function that is part of its type's namespace for example `.fixed()` or `.layout()`
- ability to initialize a parameter by calling a function that is part of its type's namespace for example `.fixed()` or `.Layout()`
- ability to initialize a parameter by using a public constant that is part of its type's namespace for example `.grow`
