Summary:
This extracts the core changes from https://github.com/facebook/yoga/pull/1116, to support gap/row-gap/column-gap, mostly identical, apart from the rename of gaps -> gutters.
The core functionality in this PR looks to be well tested from the fixtures added. I am not an expert in the internals of Yoga, but I am seeing everything that I would expect to. The space for the gap is accounted for in line-breaking, and the accumulated gaps limit the available line-length, before sizing flexible children, so items are sized correctly as to accommodate the gap. Then the gap is used for spacing during main axis and cross-axis justification.
Changelog:
[Genral][Added] - Implement gap/row-gap/column-gap (within the yoga C ABI)
