commit b59079bdb5621cd2da9664eabacfbf00f947f963
Author: Felipe Borges <felipeborges gnome org>
Date: Tue Oct 23 11:41:28 2018 +0200
account: Generate a default user profile picture
Generate a default user account picture composed of a background
color and the user's initials.
The background color is defined by mapping the hash of the user
name with an existing colour in our palette[0].
A new avatar is generated whenever the user full name entry focuses
out.
These changes are based on the mockups for the Settings Users panel[1].
