This should finally close #1115 by adding a tutorial on how to use premultiplied alpha in pygame applications to fix alpha composition errors and slightly speed up your blitting.

I tried to make these images as small as possible to keep the overall download small. I think some sort of visual was needed though.

I like the casual inclusion of wraplength functionality! Nice modern examples using the quality of life stuff.

Gave it a read through. Only thing that immediately popped up to me is that in some places you construct pygame.Color objects to pass to fill and in others you don't.

Merge when you're ready.
