1298507 - Support tab-switching in the GPU process

Status: RESOLVED FIXED

(Core :: Graphics: Layers, defect)

Description

[David Anderson [:dvander] - inactive, e-mail if emergency]

Right now tab switching does not work in the GPU process because we don't support layer tree observers. bug 1279086 will replace layer tree observers with an API that is much, much easier for us to support.

If bug 1279086 takes longer than expected we should cherry-pick those API changes out so we can get GPU process support sooner. Otherwise it's better to just wait than add complicated support for the old API.

I wasn't sure whether the in-process case needs to go through the event loop or whether it can go through IPDL too. If it can I can delete TabParent::ObserveLayerUpdate.

Yeah, go ahead and delete TabParent::ObserveLayerUpdate and the XRE_IsParentProcess() checks.
