            Bug ID: 222631
           Summary: Experiment with using half precision floating point
                    for out of line color data
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: sam at webkit.org

The CSS spec only mandates 16 bits of precision per channel for non-legacy sRGB color data, but we currently use 32 bits. We should experiment with adding support for half precision floating point a.k.a __fp16.
