Support for HD/4K Textures?

I’ve used emulators such as Project64, and Dolphin, that support custom/HD textures, and I was wondering…
I’m sure many Citra users would like to see HD/4K textures in their favorite 3DS games, so I’d like to ask. Is HD/4K texture (pack) support planned for Citra?

That’s only for rendering, not for resources (which would have to be redrawn in a lot of cases).

@Selby once worked on a texture upscaling branch (unofficial build), however there are more important issues left in Citra so we won’t focus on such features now. Same goes for “texture packs” which even need a GUI or more file handling code.
