The `SkRect::intersect` and `SkIRect::intersect` methods return values that must be handled or the calling code might end up with a non-empty answer for non-intersecting rectangles. There were 3 or 4 places in our code that we weren't doing this so now we check them all, in some cases even if we believe that the answer will not be empty. This is prep work so that Skia can add `[[nodiscard]]` directives to these 2 methods so that nobody else makes that mistake.
Flow
Flow is a simple compositor based on Skia that the Flutter engine uses to cache recorded paint commands and pixels generated from those recordings. Flow runs on the raster thread and uploads information to Skia.
