// of the same size, then we rotate the child 45 degrees around it's center, the child
|
|
// must now be cropped to a non rectangular 8 sided region.

// - WindowManager only uses rotation in one case, which is on a top level layer in which

// cropping is not an issue.

// (picture-in-picture) mode.
