color can not be vector of LinePattern

[ctarn]

When I specify the color of plots such as pie, it will run into a StackOverflowError:

import Makie, CairoMakie

fig = Makie.Figure()
ax = Makie.Axis(fig[1, 1]; autolimitaspect=1)
lp = [Makie.LinePattern(; direction=Makie.Vec2f(1, -1), width=2, tilesize=(12, 12), linecolor=:white, background_color=c) for c in Makie.wong_colors()]
Makie.pie!(ax, Vector(2:8); color=lp)

display(fig)

ERROR: StackOverflowError:
Stacktrace:
 [1] float32type(::Type{DataType}) (repeats 79984 times)
   @ Makie ~/Documents/Projects/Makie.jl/src/conversions.jl:704

Thus we have to draw such a plot many times to attach a LinePattern:

import Makie, CairoMakie

fig = Makie.Figure()
ax = Makie.Axis(fig[1, 1]; autolimitaspect=1)

vs = Vector(2:8)
lp = Makie.LinePattern(; direction=Makie.Vec2f(1, -1), width=2, tilesize=(12, 12), linecolor=:white, background_color=:transparent)
# draw the inner pie twice since `color` can not be vector of `LinePattern` currently
Makie.pie!(ax, vs; color=Makie.wong_colors()[eachindex(vs)])
Makie.pie!(ax, vs; color=lp)

display(fig)

It would be much more complex if we wanted to use different LinePatterns for different parts.

Until we have support in the backends for one linepattern per poly, we should at least throw a proper error...

Thank you! Now we can alternatively plot each part at one time respectively (in the same axis), e.g., the example. How far are we from one linepattern per poly?

It's not on any roadmap, should probably take a day of work or so ;)
