This is something I've been thinking about working on again. I'd like to work on some of Hypatia's newer textures, if she has any (she does post a lot of updates!), and I'd also like to do something with the default textures so that people don't need to use a high-resolution texture pack to get the proper aspect ratio for stuff at 16:9.
I've also thought about throwing together a small tool that will take a custom batch of images and perform the few small "aspect correction" operations. This way, people could throw some interface/HUD textures into a program, and it'd spit out textures that would look cleaner when forcing 16:9. The caveat to this, however, is that this sort of thing only works for games that necessitate the use of certain widescreen hacks, such as Twilight Princess, Wind Waker, Luigi's Mansion, Super Mario Sunshine, et. al. Dolphin's built-in widescreen hack doesn't cause stretching in the first place, although it's also generally not as effective as what you'll find with AR codes or when using the Swiss ISO widescreen hack.
Would there be interest in a small tool like that, though? Even though its use would be fairly niche at this point, it may still benefit some.
