-// This file is a snapshot of an AIDL file. Do not edit it manually. There are
-// two cases:
-// 1). this is a frozen version file - do not edit this in any case.
-// 2). this is a 'current' file. If you make a backwards compatible change to
-//     the interface (from the latest frozen version), the build system will
-//     prompt you to update this file with `m <name>-update-api`.
-//
-// You must not make a backward incompatible change to any AIDL file built
-// with the aidl_interface module type with versions property set. The module
-// type is used to build AIDL files in a way that they can be used across
-// independently updatable components of the system. If a device is shipped
-// with such a backward incompatible change, it has a high risk of breaking
-// later when a module using the interface is updated, e.g., Mainline modules.

+ * Here height=10 and width=6.
+ *
+ * If the screen orientation changes to landscape (a 90 degree orientation
+ * change), the frame's dimensions will become 6 x 10
+ * and the data will look as follows:

+ * <--        width          -->
+ *
+ * Here the element "0" is at the physical top left of the unrotated screen.
