Add support for `^(::Rotation, ::Real)`

Hi, recently I've found a need for scaling rotations described by unit quaternions, by which I mean produce a rotation along the same axis only with a different angle. I've...

As discussed [here](https://github.com/JuliaGeometry/Rotations.jl/pull/219#discussion_r806588736), it seems better to remove `rand(::RotXY)` method etc. Related: https://github.com/JuliaGeometry/Rotations.jl/issues/155

These are TODO for the documentation: - [ ] `Rotations.ErrorMap` and related things (cf. https://github.com/JuliaGeometry/Rotations.jl#the-rotation-error-state-and-linearization) - [ ] Derivation such as `Rotations.jacobian`. - [ ] Fill (TBW) in the docunent...

As discussed in #210, it's better to follow the order of `SVector`. ```julia julia> aa = AngleAxis(2.4, 0, 0, 1) # angle, x, y, z 3×3 AngleAxis{Float64} with indices SOneTo(3)×SOneTo(3)(2.4,...

Add more abstract subtypes of `Rotation`?

# The problems ## type conversion On the current `master` branch: ```julia julia> UnitQuaternion(RotX(2π)) 3×3 UnitQuaternion{Float64} with indices SOneTo(3)×SOneTo(3)(1.0, -1.22465e-16, 0.0, 0.0): 1.0 -0.0 0.0 0.0 1.0 2.44929e-16 -0.0 -2.44929e-16...

*(originally posted on [this comment](https://github.com/JuliaGeometry/Rotations.jl/pull/175#issuecomment-975114142))* I think we need to distinguish among exported method, non-exported method and internal use method. * exported method * e.g.`RotXYZ`, `nearest_rotation` * These methods should...

Change the order of `QuatRotation` from `(w,x,y,z)` to `(x,y,z,w)`

To be able to set the orientation of an object in a 3D scene of Makie.jl I use the following code: ``` q0 = Rotations.params(QuatRotation(state.orient)) # returns an SVector in...

Make rotations in degrees exact

This PR adds a second type parameter to angular rotations type (`Angle2d` and all `RotX` etc.). This prevents automatic conversion of the angle to floating-point and the resulting inexactitude when...
