How do programs like Blender (even older 2.7x versions from 2014 that
still work on my circa 2007 HP desktop computer) scale their screen
content up and down so smoothly? If you go into the Node Editor, for
example, scaling up and down is totally smooth.

And how do programs like Compiz on Linux smooth their screen animations
so smoothly? From wobbly windows, stretch and skew, etc.

Whenever I load textures into Open GL I generate mipmaps and no matter
what resolution I use on the texture, it's never as good as the
original. I can try and project a single rectangle on the screen of the
exact proportions the texture would be, and it's like the texture has
been reduced down by to a 2x or 4x lower resolution.

I'd like to be able to load in a high resolution texture and manipulate
it in high resolution.
