How to avoid zeros while using log on axis?

Is there way to avoid zero in data go -Inf and still have log axis during plotting?

Fix #3000 This implements what's suggested on Slack, namely, detect if trans…formation is one of the dangerous logs (example of non-dangerous log is `Makie.pseudolog10`), if so, use the minimal non zero value divided by 2 as the "bottom" to avoid illegal transformation `0 -> -Inf` when applying the log. Some examples that used to error but now works: ```julia using CairoMakie a = "/tmp/jl_k9M7ELsL2h.png" save(a, hist(randn(10^6); axis=(; yscale=log10))) save(a, hist(randn(10^6); axis=(; yscale=log2))) save(a, hist(filter!(x-> x<0 || x > 1.5, randn(10^6)); axis=(; yscale=log10))) ``` ![image](https://github.com/MakieOrg/Makie.jl/assets/5306213/f0d5b033-22a5-40ee-bb9b-83d5eebab175) ![image](https://github.com/MakieOrg/Makie.jl/assets/5306213/67b3cd16-aa4b-4193-a967-7327b3c26886) ![image](https://github.com/MakieOrg/Makie.jl/assets/5306213/0019c19b-7ada-41e0-9919-68ce32f7c43b)
