Summary Extended colors should be clamped so they look the same in SDR and HDR layers

Created attachment 475068 [details] test case 1. Enable Support HDR images 2. Open the attached test case Result: The background extended color `color(srgb 5 5 5)` looks brighter in the HDR layer. But the same extended color looks clamped in the SDR layer. Expected: The extended colors should be displayed the same regardless of the HDR-ness of the layer. Ideally an HDR layer should be created if any extended color is going to be displayed in this layer. Till this happens, extended colors will be clamped.
