fix warning when zooming in WGLMakie

[SimonDanisch]

This was a weird bug.
This warning popped up on master:

julia> ┌ Warning: Error in window event callback
│   exception =
│    All non scalars need same length, Found lengths for each argument: (5, 4, 1), (Vector{Makie.GlyphCollection}, Vector{Point{3, Float32}}, Quaternion{Float64})
│    Stacktrace:
│      [1] error(s::String)
│        @ Base .\error.jl:35
│      [2] macro expansion
│        @ c:\Users\sdani\Programmieren\MakieMaster\dev\Makie\src\utilities\utilities.jl:209 [inlined]

But:

• Only appeared for first call to a plotting function when zooming the first time into plot
• Doesn't appear in GLMakie, even though most of the code is the same
• seemed to be non fatal as far as I can tell ( i guess it just updated later then)

Anyways, this fixes it and should be more correct!

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(display(fig))
