void GPU_viewport_colorspace_set	(	GPUViewport *	viewport,
		const ColorManagedViewSettings *	view_settings,
		const ColorManagedDisplaySettings *	display_settings,

HACK(fclem): We copy the settings here to avoid use after free if an update frees the scene and the viewport stays cached (see #75443). But this means the OCIO curve-mapping caching (which is based on CurveMap pointer address) cannot operate correctly and it will create a different OCIO processor for each viewport. We try to only reallocate the curve-map copy if needed to avoid unneeded cache invalidation.
