Scanning the renderer of a render layer and its descendants for HDR contents is costly. To optimize the PLT, the traversal for HDR content can be disabled until an HDR image is loaded or an HDR canvas context is created. A flag can be kept on the Page to tell whether the page hasPaintedHDRContent() or not. This flag can be used by Page::canDrawHDRContent() which is consulted for before starting the traversal for HDR content.
