(Todo, find image sample of why it looks bad)
To solve this, mipmaps are created. Mipmaps are versions of the image shrunk by half in both axis, recursively, until the image is 1 pixel of size. When the 3D hardware needs to shrink the image, it finds the largest mipmap it can scale from, and scales from there. This improves performance and image quality.

Godot automatically creates mipmaps upon load for standard image files. This process is time consuming (although not much) and makes load times a little worse. Pre-importing the textures allows the automatic generation of mipmaps.
