Crossfade transition: Transition strategies

[tizu69]

Describe the problem

I'm always frustrated when I want to animate a button that turns into a card on click, mainly because there are no built-ins for this sorta stuff. theres crossfade, but it would stretch the text instead of just moving it. However, that is the only thing preventing this. Copying the transition into my own project and making a simple three-line change fixes this - I can now have funny feedback buttons :p
However, it would obviously be neat to have this in base svelte.

Describe the proposed solution

Transition strategies, which impact how the transition transitions. Next to the default scaling, resizing the elements could be another option, which looks nicer with text (depending on use case, obviously.)
There may be others to consider in the future, but I at the moment only would be interested in resizing.
