John Firebaugh	9dfc2d924d	[core] Collection-level immutability ... Introduce a second level of immutability, over each of the collections held by a style: sources, images, and layers. Tracking immutability at this level allows us to short-circuit significant portions of the RenderStyle update logic via a simple equality check, greatly improving performance.	2017-06-05 19:38:08 -07:00
John Firebaugh	095dc7b167	[core] Replace createRender{Source,Layer} with Render{Source,Layer}::create ... * Eliminates the need for EnableImmutableFromThis * Eliminates the dependency of {Source,Layer}::Impl on corresponding Render class (circular dependency)	2017-05-12 11:26:27 -07:00
