           Summary: Fix iOS depth buffer clearing issue.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: achristensen at apple.com

On iOS, the depth buffer is not being cleared correctly in WebGLRenderingContext::clearIfComposited because it is always returning after the check for !m_context->layerComposited().  This moves where the layer is being marked as composited from the mac-specific GraphicsContext3D::prepareTexture to the mac and iOS specific display function, which calls drawInCGLContext through its [super display] call.
