Bug 1315668 construct menuitem style contexts from paths r=stransky a=lizzard instead of using the context belonging to a widget. Only the style context is cached, instead of the whole widget. Using the style context from a widget meant that rendering displayed the initial appearance of animations after state changes, but there was no invalidation to trigger the final rendering in the animations. Style contexts constructed from paths do not incorporate animations. (See gtk_css_path_node_update_style() in GTK.) Therefore they provide the appropriate rendering for Gecko's model, which is not expecting animations. There is no mechanism available to display animations when using style contexts constructed from paths, but the GtkWidget animation design is also not suitable for rendering potentially multiple elements each in a different state of their animation. This contexts-from-paths approach can be extended also to other widget types, but this is a smaller change intended for uplift to other branches to address a regression in menuitem rendering.

Bug 1315668 CreateStyleForWidget: store classes on context instead of path r=stransky a=lizzard CreateStyleForWidget() then provides the same behavior with g_style_context_save() as contexts from widget root style nodes. MozReview-Commit-ID: 6lRCp3XOoRr

Bug 1315668 use style context instead of widget for menuitem dimensions r=stransky a=lizzard This is necessary to switch from caching GtkWidgets to caching GtkStyleContexts only. MozReview-Commit-ID: 6Rwinr4AY8l

Bug 1315668 remove use of gtk_container_get_border_width from menuitems r=stransky a=lizzard The GtkContainer border-width property defaults to zero. It is not influenced by theme CSS. While theme engines can theoretically modify default values for properties of any class, I don't think that is something that needs to be supported. Removing this code is necessary to switch from caching GtkWidgets to caching GtkStyleContexts only. MozReview-Commit-ID: IxgM8qjfK3a

Bug 1306314 - Allow Widevine CDM process to contain multiple CDM instances and to have persistent storage. r=gerald, a=gchang This change ensures that we don't create a new random node Id for every MediaKeys object using Widevine - which has the effect of ensuring Widevine CDMs that are same origin get created in the same process, and that persistent storage can be used and retrieved.

Bug 1306314 - Use decryptor ID in WidevineAdapter to link decryptors with decoders. r=gerald, a=gchang Store a mapping of decryptor ID to the CDM instance that the corresponding WidevineDecryptor is using. This allows us to link GMPDecryptor instances with the corresponding GMPVideoDecoder. The CDM is stored inside the CDMWrapper, so that we destroy the CDM instance when the last reference to the CDM is dropped. MozReview-Commit-ID: FQYzh77yjoC
