errorbars buggy for large x values

[cailmdaley]

using Makie, CairoMakie

start = 4e6
errorbars(start:start+9, randn(10), randn(10))

Things look good for smaller values of start; the error bars only start getting weird around start=1e5.

could be that this is because the coordinate transforms are done in Float32, at least that's usually what causes such "quantization" problems in Makie (GPU needs everything in Float32)

Fixed in Makie 0.21 via #3681
