I tried rewriting the docstrings for `should_dim_convert()` and `@convert_targets` to make them clearer but I'm not sure if I actually correctly understood them. So please take another look at them....

I've been thinking about whether `Transformation`s should be part of what `space` controls or not, and I'm leaning towards separating them. Conceptually I see `Transformation`, i.e. the transform_func, translate!, rotate!...

With higher test accuracy this fails https://github.com/MakieOrg/Makie.jl/blob/83fc003e775c9468aa362a15b45b9e8d675234c6/ReferenceTests/src/tests/examples3d.jl#L461-L472 because the axis limits have become a bit larger, changing the generated grid. I assume this happens because the data_limits of the contour...

> We kind of deprecated rotation for meshscatter in 0.20! We did? Neither NEWS nor the blog post mentions this. There should be an error/deprecation message for this, yea. Also...

`space 3D` failing is expected because the near and far planes are now tight to the `finallimits` in Axis3. This should also change OIT there, but I don't think we...

Should we merge this?

Could we add something like `plot!(..., passthrough = (; internal_attrib = ...))` to skip this check? I think otherwise this breaks some of the hackier stuff where you overwrite defaults...

> @ffreyer I'd go case by case through the errors this throws, I'm not sure in what cases what you wrote is applicable. Maybe some can be refactored? Some will...

For something like ```julia on(my_obs) do ... val = to_value(get(plot.attributes, :special_key, default)) ... end ``` that's fine but for ```julia onany(my_obs, get(plot.attributes, :special_key, default_obs)) do ... ... end ``` it's...
