(enabled for windows builds only) #Add added option to highres screenshot code to choose to output as hdr / openexr #Add 2 new visualisation modes, scene depth world units and custom depth world units. #add cvar 'r.BufferVisualizationDumpFramesAsHDR' to enable hdr export from console. #change FRCPassPostProcessMaterial can specify an override output texture format if required. #add SaveImage function to FHighResScreenshotConfig [CL 2252882 by Allan Bentham in Main branch]
