Instead of many creation options (with alpha, with multisampling, etc) use a single flag with boolean operators. Creation of the new mipmap flag for FrameBuffer, rendering the current FBO into multiple sub-resolutions.
All filters now derive from FrameBufferFilter, which is always used in a CloneSource. Default FrameBufferFilter is Passthrough filter. Others are Delay and Image filters. Implemented UI selection of filter type, XML session save and load. Linked ImageFilter to Code editor.
