+ *
+ * The transform is a user-specified 2D plane transform that will be applied
+ * to the camera images by the processing pipeline before being handed to
+ * the application. This is subsequent to any transform that is already
+ * required to fix up any platform-defined rotation.
+ *
+ * The usual 2D plane transforms are allowed here (horizontal/vertical
+ * flips, multiple of 90-degree rotations etc.), but the validate() function
+ * may adjust this field at its discretion if the selection is not supported.
