Background-related documentation issues

[NovaSquirrel]

Here are issues I ran into when working with the functions in https://blocksds.github.io/docs/libnds/group__background__api__group.html:

bgScroll() mentions that the fractional part is ignored, but the function that takes a fixed point number is actually bgScrollf(). It would also be nice if it mentioned bgUpdate()

bgSetPriority() says Higher level priority will result in background rendering on top of lower level priority. but I think it needs the additional context that lower numbers are higher priority and higher numbers are lower priority. The sprite documentation does explain this.

I don't see any mention that the fractional part is ignored, can you check that again? I'm not sure about mentioning bgUpdate(), that function needs to be called after doing anything with the background functions, basically, so I would have to mention it everywhere.

Yeah, that's true, fixed! https://github.com/blocksds/libnds/commit/e81a34445a723703454c4dbe8bedc43349b9068b

On https://blocksds.github.io/docs/libnds/group__background__api__group.html#gacde59e425f91c5c2987f5a2cef94b947 there is currently this note on bgScroll()

Ah, fair, I see what you mean. I've removed that note from bgScroll(). https://github.com/blocksds/libnds/commit/d7db4756c1d60ca6c5ab92b4989b27a4579cad80
