Image larger than GL_MAX_TEXTURE_SIZE in AnimatedSprite

If image larger than GL_MAX_TEXTURE_SIZE is loaded, it seems like it is unable to show frames past the max size, which of course makes sense.

However, the animation runs fine up to that point, but perhaps this could be improved.

Perhaps it could scale down the source image so that it fits, and/or print a warning that it will not work properly, or perhaps even refuse to load/show the animation completely (= add state property with an error state).
