How to use ndk's SurfaceControl & SurfaceTransaction

[Zakur0]

I am using the ndk-samples as a guide to create a small renderer and I wanted to be able to use the cropping functionality from SurfaceControl API.

I cannot find any source on how to use these ndk functions. Creating a SurfaceControl from aNativeWindow that is being used to create the EGLSurface fails with   SurfaceComposerClient: SurfaceComposerClient::createWithSurfaceParent error Invalid argument

Holy shit, thank you so much,
I ended up doing something similar by extending the aosp & ndk API just for the window cropping, I wasn't sure if it was an unorthodox approach.
But I had no access  to the SurfaceComposer stuff, that way.

Thanks a lot!
