iequidoo 11a8cd03af feat: Optimize avatar size multiplier for 2 << n px avatars ...

Instead of 2/3 which is not optimal for 512 px avatars usually passed to Core, use the sequence 3/4,
5/8, 4/8, 3/8... to do "smaller" downscaling steps and reduce aliasing effects.

Before, it was discussed that just 3/4 can be used. However, if we repeat the reduction step, we get
`3 << n` as a numerator and this way increase aliasing effects on each step. Better limit the
numerator to 5.
