Very easy.

- wrap a context in a Canvas with the methods for drawing.
- BLIT the cairo surface.

It also works with simple bitmaps, so image proceduraly rendered.
Actually I've started to work on this at the end of 2015.

(https://github.com/BBasile/kheops/blob/master/src/kheops/bitmap.d#L396)

While it was planned to make a native D UI, using it to plot 2D 
data would require very few work. There's also a OO wrapper 
called cairoD or something like that which is for sure very easy 
to use to render bitmap proceduraly.

The positive point with cairo is that it has a "png surfaces" so 
images can be saved in a single call (cairo_surface_write_to_png).
