CoreAnimation gives you no help at all in maintaining the correct contentsScale for layers. Anything sitting in an RBLView should have this taken care of.
Does this only apply to layer hosting? I'm pretty sure backing layers are updated properly.
Yes, hosting only.
So what would that mean with RBLView, which is meant to be layer-backed? We should update all sublayers or something?
Yeah… there is a delegate callback you can hook into and they also need setting manually when they are first created. Seems exactly like the kind of thing Rebel should handle for us.
I'm still a bit confused about the use case we're trying to solve. RBLView can't really be layer hosted, since it sets wantsLayer before anything has a chance to change the layer property.
Are we trying to fix sublayers of RBLView.layer, or layer-hosting subviews of RBLView?
The use case is that every time we want to use a layer for anything we need to handle contentsScale changes manually. Unlike anything on NSView which is handled automatically.
RBLView should handle that automatically for any of it's layers and sublayers/subviews.
