- Converted to RDG. - Converted mobile to use subresource transitions instead of awkward ping-ponging between render targets. - Merged duplicate code paths between mobile / desktop. - Eliminated FReflectionScratchCubemaps singleton in favor of explicit resource marshalling. #preflight 623cdecc573f51b292c9c84a #rb christopher.waters [CL 19513281 by zach bethel in ue5-main branch]
