+     *
+     * The transform hint can be used by a producer, for instance the GLES

+     * in the composer is identity. This can be very useful when used in

+     * cannot handle arbitrary rotations.
+     *
+     * 1. Before dequeuing a buffer, the GL driver (or any other ANW client)
+     *    queries the ANW for NATIVE_WINDOW_TRANSFORM_HINT.
+     *
+     * 2. The GL driver overrides the width and height of the ANW to
+     *    account for NATIVE_WINDOW_TRANSFORM_HINT. This is done by querying
+     *    NATIVE_WINDOW_DEFAULT_{WIDTH | HEIGHT}, swapping the dimensions
+     *    according to NATIVE_WINDOW_TRANSFORM_HINT and calling
+     *    native_window_set_buffers_dimensions().
+     *
+     * 3. The GL driver dequeues a buffer of the new pre-rotated size.
+     *
+     * 4. The GL driver renders to the buffer such that the image is
+     *    already transformed, that is applying NATIVE_WINDOW_TRANSFORM_HINT
+     *    to the rendering.
+     *
+     * 5. The GL driver calls native_window_set_transform to apply
+     *    inverse transformation to the buffer it just rendered.
+     *    In order to do this, the GL driver needs
+     *    to calculate the inverse of NATIVE_WINDOW_TRANSFORM_HINT, this is
+     *    done easily:
+     *
+     *        int hintTransform, inverseTransform;

+     *            inverseTransform ^= HAL_TRANSFORM_ROT_180;
+     *
+     *
+     * 6. The GL driver queues the pre-transformed buffer.
+     *
+     * 7. The composer combines the buffer transform with the display
+     *    transform.  If the buffer transform happens to cancel out the
+     *    display transform then no rotation is needed.

+Netlink Protocol Library
+
+This library is a clean room re-implementation of libnl 2.0 and
+re-licensed under Apache 2.0. It was developed primarily to support
+wpa_supplicant. However, with additional development can be extended
+to support other netlink applications.
+

+NETLINK OVERVIEW
+
+* Each netlink message consists of a bitstream with a netlink header.
+* After this header a second header *can* be used specific to the netlink
+  family in use. This library was tested using the generic netlink
+  protocol defined by struct genlmsghdr to support nl80211.
+* After the header(s) netlink attributes can be appended to the message
+  which hold can hold basic types such as unsigned integers and strings.
+* Attributes can also be nested. This is accomplished by calling "nla_nest_start"
+  which creates an empty attribute with nest attributes as its payload. Then to
+  close the nest, "nla_nest_end" is called.
+* All data structures in this implementation are byte-aligned (Currently 4 bytes).
+* Acknowledgements (ACKs) are sent as NLMSG_ERROR netlink message types (0x2) and
+  have an error value of 0.
+
+KNOWN ISSUES
+
+  GENERAL
+  * Not tested for thread safety
+
+  Android.mk
+  * No dynamic library because of netlink cache not implemented and
+    not tested for thread safety
+
+  attr.c
+  * nla_parse - does not use nla_policy argument
+
+  cache.c
+  * netlink cache not implemented and only supports one netlink family id
+    which is stored in the nl_cache pointer instead of an actual cache
+
+  netlink.c
+  * nl_recvmsgs - does not support nl_cb_overwrite_recv()
+  * nl_recv - sets/unsets asynchronous socket flag
+
+SOURCE FILES
