Most decoders are now created on raster threads, or at least at raster time. It's not clear they can be reused.

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

I'm changing the component on this, because I think it is WontFix but I don't feel qualified to make that call.

Yes, this is WontFix. The lifetime of ImageDecoders used on the raster threads is controlled by ImageDecodingStore, since we might be caching partially decoded frames or GIF frames for re-use later. Also, creating the decoder itself is not a heavy-weight operation, so I'm not sure what we'd gain by reusing it.
