+    // 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.
+    //

+    //   cropping is not an issue.
+    // - Launcher, as a privileged app, uses this to transition an application to PiP
+    //   (picture-in-picture) mode.
+    //

+    // of cropped areas, we need to prevent non-root clients without permission

-        // Of course we can fix this in the future. For now, we are lucky, SurfaceControl is

+
+#### Steps to run
+1. Build the fuzzer
+```
+  $ mm -j$(nproc) surfaceflinger_fuzzer
+```
+2. To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/surfaceflinger_fuzzer/surfaceflinger_fuzzer
+```
+
+# <a name="DisplayHardware"></a> Fuzzer for DisplayHardware
+
+DisplayHardware supports the following parameters:
