Unsafe Overwrite mixins

[Darkhax]

The renderBackgrounds and renderIcons mixin use Overwrite which is not a good idea for mod compatibility. Several mods including some of my own mixin the renderBackgrounds method to calculate effect regions on the screen for stuff like tooltips. Overwrites are also a bad idea in general for mod compatibility.

Thanks for the info. I had issues with those two particular methods as ModifyArg/s weren't working and caused crashes with no log information. Anyway, I have found the issue (looks like methods in abstract classes can't be used as targets). Now fixed in these two commits 45297e8 7cacb3e The update will release when 1.19 comes out.
