+ * rate. Usage of this API won't introduce frame rate throttling, or affect other
+ * aspects of the application's frame production pipeline. However, because the system
+ * may change the display refresh rate, calls to this function may result in changes
+ * to Choreographer callback timings, and changes to the time interval at which the
+ * system releases buffers back to the application.
+ *
+ * Note that this only has an effect for surfaces presented on the display. If this
+ * surface is consumed by something other than the system compositor, e.g. a media
+ * codec, this call has no effect.
+ *
+ * You can register for changes in the refresh rate using
+ * \a AChoreographer_registerRefreshRateCallback.

+ * See ANativeWindow_clearFrameRate().
+ *

+ * \param window pointer to an ANativeWindow object.

+ * \param desiredMinRate The desired minimum frame rate (inclusive) for the window, specifying that
+ * the surface prefers the device render rate to be at least `desiredMinRate`.
+ *
+ * <p>Set `desiredMinRate` = `desiredMaxRate` to indicate the surface prefers an exact frame rate.
+ *
+ * <p>Set `desiredMinRate` = 0 to indicate the window has no preference
+ * and any frame rate is acceptable.
+ *
+ * <p>The value should be greater than or equal to 0.
+ *
+ * \param desiredMaxRate The desired maximum frame rate (inclusive) for the window, specifying that
+ * the surface prefers the device render rate to be at most `desiredMaxRate`.
+ *
+ * <p>Set `desiredMaxRate` = `desiredMinRate` to indicate the surface prefers an exact frame rate.
+ *
+ * <p>Set `desiredMaxRate` = positive infinity to indicate the window has no preference
+ * and any frame rate is acceptable.
+ *
+ * <p>The value should be greater than or equal to `desiredMinRate`.
+ *
+ * \param fixedSourceRate The "fixed source" frame rate of the window if the content has an
+ * inherently fixed frame rate, e.g. a video that has a specific frame rate.
+ *
+ * <p>When the frame rate chosen for the surface is the `fixedSourceRate` or a
+ * multiple, the surface can render without frame pulldown, for optimal smoothness. For
+ * example, a 30 fps video (`fixedSourceRate`=30) renders just as smoothly on 30 fps,
+ * 60 fps, 90 fps, 120 fps, and so on.
+ *
+ * <p>Setting the fixed source rate can also be used together with a desired
+ * frame rate min and max via setting `desiredMinRate` and `desiredMaxRate`. This still
+ * means the window's content has a fixed frame rate of `fixedSourceRate`, but additionally
+ * specifies the preference to be in the range [`desiredMinRate`, `desiredMaxRate`]. For example, an
+ * app might want to specify there is 30 fps video (`fixedSourceRate`=30) as well as a smooth
+ * animation on the same window which looks good when drawing within a frame rate range such as
+ * [`desiredMinRate`, `desiredMaxRate`] = [60,120].

 This allows control to be delegated to different parts of the system - such as SystemServer,

+### Layer Drawing Order
+Layers are drawn based on an inorder traversal, treating relative parents as
+direct parents. Negative z-values place layers below their parent, while
+non-negative values place them above. Layers with the same z-value are drawn
+in creation order (newer on top).  However, relying on creation order for
+z-ordering is discouraged; use unique z-values whenever possible for better
+control.
+
+Traversal pseudo code:
+```
+fn traverseBottomToTop(root):
+  for each child node including relative children,
+    sorted by z then layer id, with z less than 0:
+          traverseBottomToTop(childNode)
+
+  visit(root)
+
+  for each child node including relative children,
+    sorted by z then layer id, with z greater than
+    or equal to 0:
+          traverseBottomToTop(childNode)
+```
+
 ### Layer Lifecycle
 Layer is created by a client. The client receives a strong binder reference to the layer
 handle, which will keep the layer alive as long as the client holds the reference. The
