Bug 1308153 - part3 : implement the logic about showing the unblocking icon. Showing unblocking icon when the tab's media is blocked, and hide the icon when user clicks unblocking icon or opens that tab. MozReview-Commit-ID: LHxop9qL0uf

Bug 1308153 - part1 : notify tabbrowser when the tab was blocked. We need to notify tabbrowser about media-blocking so that we can show the unblocking tab icon. See bug1308399 for more UX details. MozReview-Commit-ID: E25lEhZLCZk

Bug 1312540 - Use GMP caps cached in content process for GetPluginVersion. r?gerald MozReview-Commit-ID: 1nDHsW527Tu

Bug 1312540 - Simplify behaviour of GMP::GetPluginVersionForAPI. r?gerald We only have one version of a GMP installed at once anyway. This version code is to support Adobe Primetime, and that's disabled. Making the behaviour of this code simpler will make it easier to have the same behaviour of the GetGMPVersion code in e10s and non-e10s mode. I will be removing this code soon, but I will do that in a later patch, so as to not complicate the uplift. MozReview-Commit-ID: 3cn7GhihWzm

Bug 1312540 - Maintain a cache of GMPs capabilities in content processes. r?gerald,r?billm In order to avoid doing a synchronous call from content process to chrome process in order to determine what GMPs are usable, maintain a cache of GMP capabilities in the content processes. We must seed the cache when content processes are created, as the GMP service is started up and GMPs are added to it before the first (or any subseuent) content process is created.

Bug 1313570 - Change the parameter of ValidateSVGFrame. r=mstange MozReview-Commit-ID: Brym9cbGRw8

Bug 1305253 - Part 2. Replace gfxContext::Save/Restore by gfxContext::PopClip. r=mstange MozReview-Commit-ID: SPfZpRsBlo

Bug 1305253 - Part 1. Use nsCSSClipPathInstance::ApplyBasicShapeClip when clip-path type is basic-shape or geometry-box. r=mstange Before this patch, shouldApplyBasicShape will be set as true when the url of a clip-path is not resolvable, for example: clip-path: url("#non-exist-id"); So we call nsCSSClipPathInstance::ApplyBasicShapeClip and early return even if the clip-path's type is StyleShapeSourceType::URL. This patch aims to correct this wrong behavior: nsCSSClipPathInstance::ApplyBasicShapeClip shoud be used only when the type of clip-path is StyleShapeSourceType::Shape or StyleShapeSourceType::Box.

Bug 1310575 - Part 2. Implement nsDisplayFilter::ComputeInvalidationRegion. r=mstange Bring back ShouldInvalidateToSyncDecodeImages check in nsDisplayFilter::ComputeInvalidationRegion. nsSVGIntegrationUtils::PaintFilter might be failure if the filter is not ready. That is, effectProperties.HasValidFilter() returns false. So we still need that check. MozReview-Commit-ID: B4Lv5qZlHRr

Bug 1310575 - Part 1. Have a new base class for nsDisplayMaskGeometry and nsDisplayFilterGeometry. r=mstange Use nsDisplayMaskGeometry, created by nsDisplayMask, in nsDisplaySVGEffects, which is the parent class of nsDisplayMask) is odd. So create a base class for both nsDisplayMaskGeometry and nsDisplayFilterGeometry. Use this base class in nsDisplaySVGEffects's code. MozReview-Commit-ID: G3FLybT1pQp
