[BUG] grid checks sum to 1 but fails due to numerical approximation.

[ignacioq]

Details

This gives command to be used in layout: grid(4, 2, heights=[0.3, 0.3, 0.3, 0.1]), returns an error because, due to numerical approximation, it does not literally sum up to one.: ERROR: The sum of heights must be 1!.

I tried this: grid(4, 2, heights=[0.3, 0.3, 0.3, 0.1 + 1e-16]) and now works, but would be nice to make an approximate comparison.
