            Bug ID: 220858
           Summary: Move FontCascadeCache onto FontCache
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org

Currently, FontCascadeCache is a singleton and is managed by some static global functions. This isn't particularly clear as it doesn't follow the convention of being a class with a singleton() method (it's just a typedef of a HashMap). I think it makes sense to integrate it with FontCache - this works well for making FontCache thread-safe, as the FontCascadeCache is also a requirement of using fonts and both can be managed easily using the same lock.
