To be fair though, you could compute the pixels for those with
just math,
there is no need to have a graphics context type abstraction.

I did not think it was possible to write a proper raytracer for
arbitrary content all as a shader program, but I do not know enough
about 3D graphics to know if that demo is correct or if that is
possible in general. Point conceded though.

Neither of examples you posted seems to have the ability to zoom in,
so I don't think they show anything about doing this to extremely
high accuracy. But I see your point that much of this particular
computation can be done on the GPU, up to probably quite high
limits. Replace this example with your choice of non-data-parallel
computation.
Following the links, this demo does do zoom, but it will go all jaggy
past a certain zoom level, presumably due to limitations of GLSL.
