now, with a 'resize' routine for the engine we can/should also recreate some buffers that are created only at init time (e.g., 2d filters, dome fbos, ...). This bug was always present in Blender (since 2.49 at least). Bugfix supported by NF-UBC Nereus Program as part of the development of OceanViz/NereusViz
