Summary: I am about to embark on supporting `position: static` in Yoga. The enum exists already (and is the default position type, lol) but does not actually do anything and just behaves like `position: relative`. My approach here is to write a bunch of tests to test for the various behaviors of static positions and then develop on Yoga afterwards to get those tests passing. To do this, we need to make a few changes to the gentest files as there is not support for adding `position: static` at the moment: * Make it so that the gentest code can physically write `YGPositionTypeStatic` if it encounters `position: static` in the style * Make it so that gentest.js knows that Yoga's default is actually static. This way the code generated in the tests will actually label nodes for non default values * Explicitly label the position type even when it is not declared in the style prop (with the exception of the default) * Regenerate all the tests Additionally I added the first, basic test: making sure insets do nothing on a statically positioned element.
