Description
It does not work, because glGetTexImage is not available for GLES. But it seems possible to replace it: https://stackoverflow.com/questions/53993820/opengl-es-2-0-android-c-glgetteximage-alternative/53993894#53993894
It would be great to have this function for GLES too (and it would make the pixelBufferExample and textureBufferInstancedExample work)...

Research direction
Start with the implementation of ofTexture::copyTo and compare its GLES path with the desktop path that uses glGetTexImage. Review the linked OpenGL ES alternative, then check pixelBufferExample and textureBufferInstancedExample. Done means copyTo works for GLES and those examples work as described.
