Simple 2x circular zoom routine

Hi all,
Can anyone point me in the right direction in implementing a basic
2-4x circular zoom routine using SDL.

I can do a rectangular zoom, but cannot figure out how to perform a
circular zoom using SDL.

I am aware of SDL_rotozoom, but wanted something a bit simpler.

Any ideas welcome.–

What exactly is a ‘circular zoom’ (compared to a rectangular one)?

I guess he means a Roto-Zoom

Is this not just a rect zoom with a circular stensil alpha mask etc?
