Visualization now buffers in the audio output pipeline, and uses a container system to delay multiple buffer chains from emitting visualization data over top of each other. This should stabilize display output significantly, while introducing minimal lag before DSP configuration changes take effect. Signed-off-by: Christopher Snowhill <kode54@gmail.com>
