[cairo] Vector scaling

[AD]

Hello,
Sorry if this feels dumb or if it's not the right place to ask. I looked
everywhere for an answer.
I understand that cairo is a vector graphics library.
So is there a way to upscale a surface with vector drawings on it (shapes
and text), without upsampling?
I'm using pycairo, to create some surfaces with text and shapes on it, and
I'd like to be able to serve PNGs of several sizes. Do I have to redraw
everything each time? Or is there a way to upscale a cairo surface without
rasterizing it?

Thanks

Eric
