I have found "Material Design Iconic Font" library which is similar to md-icon and allow to create a stacked icon: http://zavoloklom.github.io/material-design-iconic-font/examples.html
But wasn't able to create a stacked icon combining angular material icons. https://material.angularjs.org/latest/api/directive/mdIcon
I'm already using angular material icons in my project, and don't want to include another library just for stacked icon.
Is there any way/work around we can combine md-icons to create a stacked angular material icons?
