tiles: List of BaseTile subclassed objects with data to display.
led_rows: Integer size of RGB matrix hat. Default: 32.
chain_length: Integer number of matrix's attached. Default: 2.
write_cycles: Integer write cycle speed, higher is slower. Default: 2.
tile_size: Integer minimum square tile size in pixels. Default: None (same
as led_rows).
fps: Integer max number of frames to render a second, max 60. Default: 1.
Raspberry Pi's have limited processing power, so 60 is not
recommended.
static_lifespan: Integer number of seconds a static tile should be
displayed before being cleared. Default: 5 seconds.
render_pipline: List of Lists (matrix) containing Integer indexes
representing the tile to display. This matrix shape is generated from
the matrix_manager.
