Issue with cache cost calculation for UIImage created from Core Image

[rounak]

We are using PINRemoteImage's processorBlock to download an image from a URL, and then processing it using Core Image. We return UIImage(ciImage: processedCoreImage) in the processorBlock.

However we're hitting an NSAssert in PINRemoteImage during cache cost calculation:

NSAssert(container.image == nil || imageRef != NULL, @"We only cache a decompressed image if we decompressed it ourselves. In that case, it should be backed by a CGImageRef.");

It seems like this only supports UIImage that is CGImage backed, which is not the case with Core Image. Any help or guidance would be appreciated, thanks!
