I changed the indices because this method did not work properly before.  I had to increment the indices to leave room for the self object which is a MOAIFrameBuffer.  Previously, when calling it like it was before in tests like `test/source/MOAIColor/main.lua`, it did not work as I expected it to work because I kept getting a warning about an invalid cast from a MOAIImage to a MOAIFrameBuffer.  I changed this method into one that uses a colon on a MOAIFrameBuffer object rather than a class method of MOAIFrameBuffer, and reserved the first index for the self parameter.
