Upconverting Fonts and the Main Menu Bully Logo?

[Jimmy4Prez]

Using Nifscope, I've been able to upscale HUD elements and model textures with no problems.
But after adding upscaled textures to fonts.nft, in game they look like the attached image.
The game is obviously still using the same exact pixel spacing from the original 512x512 texture
(using only 1/4 of the new 1024x1024 texture).
Does anyone happen to know where this information is stored and if it can be modded?

Another issue is replacing the main menu Bully logo in fe1.txd.
Wherever the code is, it looks like the texture was just "centered" with no dimension information.

For both, It looks like each pixel is doubled as well, resulting in pixelated blurry edges.

Anyone that can provide any info to fix these issues would be greatly appreciated. Thanks.
