is it possible to set the color of a single pixel with Cairo?

Not like you would do with a classic canvas (2d grid), because colors are applied with `cairo_fill()` and `cairo_stroke()` on a particular path.

but you can define a path that represents a single pixel and fill it:

```
cairo_rectangle (cr, x, y, 1, 1); // 1 pix rectangle
cairo_set_source_rgba (cr, 0, 0, 0, 1); // color
cairo_fill (cr); // fill the rectangle with source rgba

```

However cairo is node made to be used like this. The workflow is usually more based on stacked layers (1 layer = 1 path) with different filling, different transparency.

I did something similar here : https://github.com/Zardoz89/DEDCPU-16/blob/master/src/lem1802_fontview.d#L287

I need to clean these code...
