[glam] is a simple and fast linear algebra crate for games and graphics.

This month version 0.21 of glam was released. Because glam is not a generic

library, when support was added for `f64`, `i32` and `u32` types back in glam

0.12, macros were used internally to avoid a lot of code duplication. This

unfortunately obfuscated the internals of glam for anyone who needed to view the

source.

As of the 0.21 release the majority of glam code is now generated using an

offline tool and committed to the repo. The macros that were used to define

glam's internal implementation are gone. This means what users see when reading

docs or stepping through glam in the debugger is plain old Rust code. Many

functions have also been made `const fn` removing the need for macros to create

`const` values.
