SurfaceTexture can now force the client to request a buffer
SurfaceTexture now has the concept of default size a new method,
setDefaultBufferSize() to set it. When the default size is
changed, dequeueBuffer() will return a value telling the
client that it must ask for a new buffer.
The above only applies if the client has not
overriden the buffer size with setGeometry.
