Floating precision error causing oversized layout main dimension (totalFlexShrinkScaledFactors)

[Hexlord]

There are cases where subtraction from totalFlexShrinkScaledFactors causes the value to apporach zero but not quite reach it, flexLine.layout.totalFlexShrinkScaledFactors == 0 should instead be <= 0.001
Happens only under extreme conditions (resizing panels to 0 width)

flexLine.layout.totalFlexShrinkScaledFactors == 0) {

We have yoga::inexactEquals that we could use for this. The way it works is a bit of a sledge hammer, but it's the right overall check here if we can accumulate FP error.
