See the Makie figure below. Why the square marker is visually much larger than the diamond? Overall, the sizes of all markers are not visually pleasing. Can we have a better default size for each default marker?
Yes I would like that too. The issue is that we map markers to glyphs from dejavu sans, and they are not size matched. A better way would be to construct these shapes ourselves and control them exactly. I have started doing that a while ago in https://github.com/JuliaPlots/Makie.jl/pull/979
But it’s not clear yet how that could map to GLMakie as it doesn’t have bezier primitives and one would need to prerender the shapes to bitmaps. Currently we use FreeType for doing that with glyphs.
