Subscript/superscript combinations

[jkrumbiegel]

This PR adds the subsup and left_subsup rich text functions which allow to create combined sub/superscripts which are common in fields such as chemistry. Fixes #2718

You cannot have line breaks in them so I'm just avoiding the complications that would come from allowing that.

Looks like:

text(2, 2,
        text = rich(
        left_subsup("92", "238"), "U",
        "  ",
        left_subsup("13", "27"), "Al", superscript("3+"),
        "  ",
        left_subsup("53", "127"), "I", superscript("−"),
        "  ",
        "x", subsup("tfk", "py"),
        "   ",
        "a", superscript("2"),
        "   ",
        "b", subscript("3"),
        "   ",
        "c", subsup("A", "B"),
    ),
    fontsize = 30,
    align = (:center, :center),
    axis = (; xscale = log10, yscale = log2, xgridvisible = false, ygridvisible = false),
)

Compile Times benchmark

Note, that these numbers may fluctuate on the CI servers, so take them with a grain of salt. All benchmark results are based on the mean time and negative percent mean faster than the base branch. Note, that GLMakie + WGLMakie run on an emulated GPU, so the runtime benchmark is much slower. Results are from running:

using_time = @ctime using Backend
# Compile time
create_time = @ctime fig = scatter(1:4; color=1:4, colormap=:turbo, markersize=20, visible=true)
display_time = @ctime Makie.colorbuffer(display(fig))
# Runtime
create_time = @benchmark fig = scatter(1:4; color=1:4, colormap=:turbo, markersize=20, visible=true)
display_time = @benchmark Makie.colorbuffer(fig)
