- Weaken type constraints on `perspective` function to take an `Into<Rad<S>>`. - Weaken type constraints on `perspective` function to take an `Into<Rad<S>>`.
- Add `Angle::new` for constructing angles from a unitless scalar.
### Changed ### Changed
- `Vector`, `Point`, and `Angle` are now constrained to require specific
operators to be overloaded. This means that generic code can now use
operators, instead of the operator methods.
- Take a `Rad` for `ProjectionFov::fovy`, rather than arbitrary `Angle`s. This - Take a `Rad` for `ProjectionFov::fovy`, rather than arbitrary `Angle`s. This

overloaded. This means that generic code can now use operators, instead of from `Deg` and `Rad`. This is because angles do not close over multiplication,
the operator methods. and therefore cannot have a multiplicative identity. If we were truly accurate,
`Angle * Angle` would return an `Angle^2` (not supported by the current api).
- Moved free trigonometric functions onto `Angle`.
