How to draw to a texture of screen size?

[bakerw]

How do would I draw to a texture of the screen size (greater than 1024x1024), going to be a background for some graphing software rather than drawing a few hundred lines per frame, or is SFML not a good option for this?

Why do you need to draw to a texture (which only works with a render texture) and can't just draw to the window?
There is a maximum texture size, but it's not fixed to 1024x1024. Since it's a specific software you could also require for the workstations to have enough recent GPUs that will easily support screen size large textures.
