UIImage RenderingMode not persisted in cache

[lifely]

Hi,

First thanks for that pretty cool library, seems to perfectly fit the job i was looking for with a pretty interfaces around it.

I wanted to report a bug where the image attributes are lost when using hnk_setImage:withKey:.
In particular i'm referring to the image Rendering mode.

I'm extensively using the renderingMode - UIImageRenderingModeAlwaysTemplate in my app.

while using Haneke 1.0.0 this is my temporary solution :

[imageView hnk_setImage:image withKey:key placeholder:nil success:^(UIImage *image) {
    imageView.image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
} failure:nil];
