            Bug ID: 241560
           Summary: Avoid using hardware JPEG decoding in the WebContent
                    process
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Images

We disable hardware JPEG decoding so that we can block IOSurface uses in the WebContent process. We missed a scenario where using a file picker might need to create an image thumbnail/icon, which now triggers a sandbox violation potentially crashing the WCP.

This patch instructs CoreGraphics to use the software path, similar to how we fixed Bug 238489.
