Description
Report
CSS defines both start/end and flex-start/flex-end alignment keywords. The difference is that the flex-* versions are affected by both direction and flex-direction whereas the other versions ignore flex-direction.
Yoga only has FlexStart and FlexEnd variants in it's Align and Justify enums, and this issue is a request for Start and End to be added (and also to check that Yoga's FlexStart and FlexEnd do actually correspond to flex-start and flex-end semantics).

Research direction
Start with Yoga's Align and Justify enums and trace how FlexStart and FlexEnd are resolved against direction and flex-direction. Compare that behavior with CSS start/end versus flex-start/flex-end, then consider the work complete when Start and End variants have the requested semantics and existing Flex* behavior has been verified.
