Bug 887889 - Migrate ContentPrefService2 to Sqlite.jsm r=mak - I kept the xpcom-shutdown observer around even though it's not doing much and it could be satisfied by doing a little more work in the Sqlite.shutdown blocker. I wasn't sure which to use since it seems like the Sqlite.shutdown blocker is intended to be used to cleanup connection-related things. Thoughts on this are welcome. MozReview-Commit-ID: CqcGHBFaJsZ

Bug 1425866: Just null-check the CSS Loader for now. r=heycam After discussing with Olli there isn't any kind of severe problem out of this. Shadow subtrees will be disconnected just like the rest, and they shouldn't assume that the document hasn't been disconnected first. MozReview-Commit-ID: CX4fXOqEIFj

Bug 1456703 - Remove nsIDOMXULTextBoxElement r=enndeakin+6102 MozReview-Commit-ID: 6ZRzVq1bJjz

Bug 1456703 - Stop using nsIDOMXULTextBoxElement to detect XUL textboxes r=enndeakin+6102 This is used in JS via instanceof checks, and in C++ only to get the `inputField` attribute (the actual HTML input or textarea). We can swap out instanceof by checking the tag name, and we can directly query for the input field from C++. MozReview-Commit-ID: 7xpHQMYzYhD

Bug 1435094 - wire up GlyphRasterSpace to nsDisplayTransform. r=kats,mstange When a transform thinks it's animated we should abandon screen rasterization and instead favour local rasterization. This produces a more visually pleasant rendering, as pixel-snapping "wobbles" the text between frames. The float scale of GlyphRasterSpace::Local is currently unused, but this PR tries its best to set it to a reasonable value, based on discussion with glennw about the intended semantics. We agreed it should specify the scale *relative* to the parent stacking context, which means it's just whatever scaling the stacking context's transform applies. It's possible we'll need to clamp this value or make it properly 2-dimensional later on. Some book-keeping is added to StackingContextHelper to ensure that GlyphRasterSpace::Screen is never requested by a descendent of a stacking context using GlyphRasterSpace::Local. nsDisplayMask is changed to use a StackingContextHelper to ensure rasterSpace is properly propagated. In addition, this is the first commit making use of cbindgen's new support for bridging Rust enums natively into C++! This bumps our minimum cbindgen to 6.0.0 (just released).

Bug 1457102: Ensure a style flush happens after a compat mode change. r=heycam This is the actual fix. The compat mode changed (well, it didn't), but we were not scheduling a style flush. Then someone called getComputedStyle on an element in this document, and the styles were thought clean, thus we didn't flush style, and we assert when style resolution happened.

Bug 1457102: Avoid all the work if the compat mode hasn't actually changed. r=heycam In this case the stylist is marked dirty because a compat mode change. The change just doesn't exist (NavQuirks -> NavQuirks). So avoid the work in the first place. MozReview-Commit-ID: lchKJECNkO
