		It is followed by a number of rows of the form:

		TYPE COUNT PAUSE PATH [#RGBHEX [CLOCK1 [CLOCK2]]]
		TYPE COUNT PAUSE PATH [FADE [#RGBHEX [CLOCK1 [CLOCK2]]]]

		* TYPE: a single char indicating what type of animation segment this is:
		+ `p` -- this part will play unless interrupted by the end of the boot
		+ `c` -- this part will play to completion, no matter what
		+ `f` -- same as `p` but in addition the specified number of frames is being faded out while
		continue playing. Only the first interrupted `f` part is faded out, other subsequent `f`
		parts are skipped
		* COUNT: how many times to play the animation, or 0 to loop forever until boot is complete
		* PAUSE: number of FRAMES to delay after this part ends
		* PATH: directory in which to find the frames for this part (e.g. `part0`)
		* FADE: _(ONLY FOR `f` TYPE)_ number of frames to fade out when interrupted where `0` means
		_immediately_ which makes `f ... 0` behave like `p` and doesn't count it as a fading
		part
		* RGBHEX: _(OPTIONAL)_ a background color, specified as `#RRGGBB`
		* CLOCK1, CLOCK2: _(OPTIONAL)_ the coordinates at which to draw the current time (for watches):
		+ If only `CLOCK1` is provided it is the y-coordinate of the clock and the x-coordinate
