* fix: handle embedded cubemap face order correctly * chore: do not treat cubemaps as separate logic when not necessary * chore: make sure face major image data is the default and chosen for any game other than qos * chore: make new tests use no namespace --------- Co-authored-by: Jan Laupetin <[email protected]>
