Add 2nd source/image to page peel shader (and maybe other similar ones)

[Destroy666x]

The non-transition one has limited paramers and just works on the source where it's applied. The transition one has double source option, but it can't be used as a regular dynamic filter as it's just stopped.

So you can't define a non-transition filter that animates and uses another source as a "reveal". A sort of combination of both would be great. I suggest adding either:

• 2nd source (or at least still image) to filters like the page peel one
• a way to animate the transition shaders inside of filters, maybe with a checkbox option

You can use move value filters to animate the transition version. I will think about what would be the best way to get the effect with only this plugin.
