Bug ID: 227062
Summary: [css-scroll-snap] Simplify snap point selection
helpers
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Scrolling
Assignee: webkit-unassigned at lists.webkit.org

We can combine the two snap point selection helpers indicesOfNearestSnapOffsets and searchForPotentialSnapPoints, reducing the amount of times that we walk the snap point list and making it more obvious what the return values of the arguments are. In addition, we can have this method return the geometric next and previous snap offsets if they exist, rather than two offsets that might both be greater or lesser than the target. This is useful because parts of the specification refer to these two values when implementing certain features. This makes the code a lot easier to read and very slightly more efficient.
