           Summary: [Qt] Support kerning in fast path font rendering
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Text
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: allan.jensen at digia.com


The fast path font rendering has support for kerning, but to do so requires the SimpleFontData::applyTransforms method. Fortunately the method is available in QRawFont under the name advancesForGlyphIndexes. By tweaking the GlyphBufferGlyph and GlyphBufferAdvance types similar to what Safari does, this method can be called directly.
