The rendering order for Spx1 is that sprites created first are displayed in front, while for Spx2, sprites created later are displayed in front. The second method is more intuitive and aligns with the default rendering approach of most engines.

Is there a specific reason for Spx1's design? If not, should it be changed to follow the conventional engine rendering method?
