it's probably not chrome because they are using this third party library: (https://github.com/fmtlib/fmt). also, it might be that this sink is actually meant to write a message to the console but due to configuration options its a noop.

Seems like this algorithm does not do that ?

> [...] Instead, we put pixels in a one-to-one relation to the points they represent. You can think of this as mapping some imaginary point on the pixel, such as its center or corner, onto the complex plane, and making the whole pixel represent that value.

7> // highest possible value of the exponent
The Float then simulates unsigned 12bit mantissa and 3bit exponent. Sure it still takes 16 bytes. But you could create a union with bitfields, where you shrink that even further.
