Fix absrect for select_rectangle

[SimonDanisch]

Fixes https://discourse.julialang.org/t/glmakie-issue-with-select-rectangle/119008
Although I don't fully understand why xy isnt a tuple in that error.

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)

Ok, the mystery got solved, this was already fixed on master :D
I think, I still want to merge the updated version, since i like the map version more.
