Bug 1371450 - Recreate style context only if the element was restyled during the traversal. r?emilio MozReview-Commit-ID: CBYTB5FeikP

Bug 1371450 - Preserve restyle hints after ForThrottledAnimationFlush restyle. r?emilio Those remaining restyle hints are needed for normal traversal later. MozReview-Commit-ID: DswGYGQwgfw

Bug 1371450 - Don't traverse normal dirty elements in ProcessPostTraversal when we process throttled animations restyle for event handling. r?emilio When we process throttled animations restyle for event handling, we skip normal traversal at all, so after Servo_TraverseSubtree, normally there remains unstyled elements which have to be processed in normal traversal later. These elements should be skipped in ProcessPostTraversal too since it's not yet styled! MozReview-Commit-ID: LgyWQpiFZ8e

Bug 1371450 - Rename TraversalRestyleBehavior::ForAnimationOnly to TraversalRestyleBehavior::ForThrottledAnimationFlush. r?birtles,emilio ForAnimationOnly is somewhat misleading, it means actually we process *only* animation-only restyle without normal restyle. The purpose of ForAnimationOnly is for updating throttled animations to get correct position of the animations when we need to handle events. Currently we do also update unthrottled animations though. MozReview-Commit-ID: HBCCluKrZs9

Bug 1355380 - Part 2: Make Servo's rounding of image-orientation values agree with Gecko's, and pass orientations directly as an enum instead of as angles. r=manishearth Both Servo and Gecko store the specified value of the image-orientation property as a single-precision float, but Gecko does the conversion to radians and the computation to identify which quarter-turn the angle is closest to using doubles. We add Angle::radians64 to perform the conversion to radians using doubles, just as Gecko does, and then update image_orientation to perform the computation the same exact way Gecko does in nsStyleImageOrientation::CreateAsAngleAndFlip. This lets the previously failing reftests pass. We also update Gecko_SetImageOrientation to take an orientation directly instead of an angle (otherwise we'd be doing the which-quarter-turn-is-closest computation twice). Finally this lets us re-enable the reftests for image-orientation previously marked as fails-if(styloVsGecko||stylo). MozReview-Commit-ID: 2zMMzQlsYEC

Bug 1355380 - Part 1: Have nsStyleImageOrientation::CreateAsAngleAndFlip handle negative angles correctly. r=manishearth Previously we just took the input angle mod 2π, which will leave negative input angles as negative. By checking if the input mod 2π is negative and if so adding 2π and then taking that mod 2π again we can ensure that we end up with a an angle in the range [0, 2π]. We only do this if the result of the initial mod is negative because this adds rounding error that is enough to mess up whether 135 is determined to be closer to 90 or 180, for example. We add a test for this as well. Also fix property_database.js to account for this (we assert that -90deg should compute to the same value as the initial value, but it should actually compute to 270deg).

servo: Merge #17696 - Sync Servo / Gecko image-orientation rounding; pass as enum (from jyc:image-orientation-redux); r=Manishearth Make Servo's rounding of image-orientation values agree with Gecko's, and pass orientations directly as an enum instead of as angles. Depends on a Gecko change to be subsequently landed in m-c.

servo: Merge #17737 - Convert TrackList's `values` field to store only TrackSize (from canaltinova:same-grid-but-better); r=Manishearth,wafflespeanut It was storing both TrackSize and TrackRepeat before and TrackRepeat have to be converted into sequence of TrackSize during serialization. Instead of doing this in serialization process(which is hard and hacky), we converted to do this in parsing process. We were doing this conversion in the ComputedValue conversion. So we only had to move this process to parsing. --- <!-- Thank you for contributing to Servo!
