// SurfaceFlinger's renderer is not prepared to handle cropping in the face of arbitrary
// rotation. To see the problem observe that if we have a square parent, and a child
// of the same size, then we rotate the child 45 degrees around its center, the child
// must now be cropped to a non rectangular 8 sided region.
//
// Of course we can fix this in the future. For now, we are lucky, SurfaceControl is
// private API, and arbitrary rotation is used in limited use cases, for instance:
// - WindowManager only uses rotation in one case, which is on a top level layer in which
// cropping is not an issue.
// - Launcher, as a privileged app, uses this to transition an application to PiP
// (picture-in-picture) mode.
//
// However given that abuse of rotation matrices could lead to surfaces extending outside
// of cropped areas, we need to prevent non-root clients without permission
// ACCESS_SURFACE_FLINGER nor ROTATE_SURFACE_FLINGER
// (a.k.a. everyone except WindowManager / tests / Launcher) from setting non rectangle
// preserving transformations.
