Separate 2D rendering areas?

[Pastaspace]

After a few tries on my own, with no luck, I've decided to ask for help.

What I'm trying to do is have a separate and smaller context/render area out on the screen. Basically anything drawn outside of the area gets cut off. So for example, drawing a 200x200 image inside of this area, if it was 100x100, would only render part of the image. I'd be using this for minimaps and similar.

 

Basically this. I have a general idea of how do to this, but then again, not really.

So what do I do? My main guess is that it involves creating and drawing to a separate buffer, but there's limited documentation on buffers.

There is a render to texture tutorial for a security cam that may be of use to you.

I already know how to do that, I'm talking about applying that to things like contexts and similar.

And I'm saying having a seperate context ontop of the current is a bad idea - instead draw a quad with the RTT texture

Yep, that works just fine!

One question though, is it possible to resize a buffer at all?
