           Summary: [Qt] font cache reworking
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Platform

We have already done some work in #24551 but I am not fully happy with the code
yet.
We created a cache for FontPlatformData objects in FontCacheQt.cpp. The problem
is that
this cache never been purged. FontCache has a tricky semantic: the elements of
the FontPlatformDataCache are removed when a SimpleFontData, which has the same
FontPlatformData is being removed from the FontDataCache (the two
FontPlatformData objects are
not the same, they are just equal). I think we should uniforming our FontCache
implementation
with the shared one for adapting this semantic.
