Prior to this PR, if AddSpinner() was called after Start() and the number of spinners exceeded the lines left on the screen rendering would break. This caused frames to be written to a new line for each frame.
This PR fixes that by ensuring that the screen is buffered inside the processing loop. The result is that we can recalculate the number of lines needed for each render cycle.
