Appearing/disappearing source zoom initial or target zoom

[stashymane]

Currently, the only zoom type you can do for sources appearing and disappearing is inwards, towards a size of 0x0.
Would be nice to have an option to set the zoom percentage for transitions, e.g. making a source only shrink by 10% while fading out, or grow by 10% in some cases. Zooming out until the source is invisible is a bit too jarring in most cases.
