Proper Anchoring of Overlays.

Whenever I create overlays for minecraft, it's always anchored to be center and I can't do anything about it. When I change the GUI scale in Minecraft graphics options the custom overlay also scales as expected. But if you want an overlay element to be at the edges of the screen, it won't stay at the edge of the screen when GUI scaling has changed in Minecraft, it'll scale into the center of the screen.

I'd like for MCreator to add for each Overlay element an option to change the anchoring to be center or bottom left or top right or etc...
