Add options to reduce edge artifacts in scatter (text, lines)

[ffreyer]

Description

Fixes/Improves https://discourse.julialang.org/t/hide-stroke-in-3d-scatter-using-makie-jl/106383

Adjusts the shader to not do AA via sdf data when fxaa = true. This avoids generating transparent pixels from AA, which generate artifacts based on render order.

So it allows you to get rid of white outlines in 3D scatters

at the cost of marker quality/detail

by setting fxaa = true.

---

From #3432:

Adds depthsorting::Bool as a hidden attribute. Setting it to true results in scatter markers getting sorted on the CPU, making them render in a non-artifacting order:

This only works between markers of the same plot call. If markers from another scatter call or another plot object is involved artifacts may reappear. Unlike the fxaa solution this does not degrade quality though:

Type of change

• New feature (non-breaking change which adds functionality)

Checklist

• Added an entry in NEWS.md (for new features and breaking changes)
• Added or changed relevant sections in the documentation
• Added unit tests for new algorithms, conversion methods, etc.
• Added reference image tests for new plotting functions, recipes, visual options, etc.

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)
