Add support for transformations in coil-gif

[damiancioo]

Is your feature request related to a problem? Please describe.
Right now I want to use coil's coil gif extension together with transformations, it seems that Gif extension is ignoring them

I did:

Coil.setDefaultImageLoader(ImageLoader(this) {
            componentRegistry {
                add(GifDecoder())
            }
        })

and load image with:

imageView.load(R.drawable.some_gif_image) {
                placeholder(R.drawable.placeholder)
                transformations(CircleCropTransformation())
                repeatCount(0)
            }

Describe the solution you'd like
Gid extension should apply transformations

Yep, I'd like to add support for this as well, however it'll need to account for ImageDecoder and more specifically PostProcessor.

PostProcessor has some key differences from Transformations:

• It passes a Canvas instead of a Bitmap.
• The canvas behaves as if the decoded image data already exists on the canvas.

Unfortunately, I won't be able to work on this for a while, but PRs welcome.

@colinrtwhite I have made suggested changes and this seems to be working fine. PR coming soon!

Hi Instacart!
This issue blocks us from switching to Coil.
Is there a planned release date for the next version?

[colinrtwhite]

@prithivraj Yep! The next release should be out either tomorrow or early next week - just need to fix one bug on master.

[colinrtwhite]

The release is delayed slightly, unfortunately as I haven't been able to solve the issue on master yet. In the meantime you can use the snapshot builds if you need the latest changes now.

Thanks for the update Colin, I've checked with the snapshot version, everything looks good and working!
