[BUG] 3D plots don't respect aspect ratio

[jonniediegelman]

Details

Try any of

plot([0.0, 1.0], [0.0, 2.0], [0.0, 100.0]; aspect=:equal)
plot([0.0, 1.0], [0.0, 2.0], [0.0, 100.0]; aspect=1)
plot([0.0, 1.0], [0.0, 2.0], [0.0, 100.0]; aspect_ratio=:equal)
plot([0.0, 1.0], [0.0, 2.0], [0.0, 100.0]; aspect_ratio=1)
plot([0.0, 1.0], [0.0, 2.0], [0.0, 100.0]; aspectratio=:equal)
plot([0.0, 1.0], [0.0, 2.0], [0.0, 100.0]; aspectratio=1)

and it will produce a cube visualization area with equal length sides with all axes scaled.

This has always (at least for the last few years) failed with the plotly backend, but now it's failing even in GR.
