Implementation in Godot should look something like:

1) Get viewport texture

2) Turn into image

3) Blit the image to the relevant part and upscale it with nearest filtering

4) Take center pixel as the color and draw graphics

Firefox has this implementation and it looks awesome:

Should this be display wide or only inside the application? And if for the whole display, should there be a zoom thingy following the mouse?
