Is it possible to render with a lower resolution within a higher resolution container/window?

[felixriehm]

Because of performance issues i would like to render a 2D scene (animated circles, lines, text, etc) with a lower resolution within a higher resolution window. Of course, the rendered images than would be stretched by some kind of interpolation to the higher resolution of the window. For example, i like to render my scene in 1080p and than stretch the rendered image to a 4k window. Is there a way to do that with nannou?

You could render into a low-res texture, and then draw that to the screen.

Have a look at the high-res capture example, you might be able to do the opposite (render to smaller texture). See #947 for an extracted version of that code.
