Corrupted marker with Point2 instead of Point2f

[ederag]

Instead of three hexagons (as shown in #2777; a similar code is used here), the result of

using CairoMakie
a = 0.5 # hexagon radius
vertices = [
	Point2(  # workaround: change to Point2f
		a * cos(θ),
		a * sin(θ)
	)
	for θ in range(1/6 * pi, 13/6 * pi, length = 7)
]
hexagon = Makie.Polygon(vertices)
points = a .* Point2[(0, 0), (sqrt(3), 0), (sqrt(3)/2, 1.5)]
scatter(points,
    marker = hexagon,
    markersize = 1,
    markerspace = :data,
    color = 1:3,
    axis = (; aspect = 1, limits = a .* (-2, 4, -2, 4))
)

is weird:

It might be related to #1419 or #2573, as it has to do with single vs double precision.
The funny thing is that here lower precision gives better results, so it might be entirely different.

Note:
This was with CairoMakie v0.10.2.

With GLMakie v0.8.2 there is an error:

Fixed in Makie 0.21, possibly by #3681

Confirmed, thanks !
