Forgot to talk about these two points:

- at present, I rely on the call to prepareContentsTexture() in useRenderSurface() to allocate the texture, and this only happens when drawLayers() is invoked().

- if m_compositeOffscreen is false, then compositing is done in the same way as at present, including compositing directly to the backbuffer.
