In packaging guide, note how to include an icon for direct distro

[ashryanbeats]

"Include at least a 512x512 icon in PNG or JPG format, no larger than 1M"

Icons will have rounded corners applied automatically in a variety of contexts. Your icon should be designed as a square, but you should take care to avoid placing important graphical elements in your icon's corners as they could be clipped when rendered in other contexts.

In order to ensure the best visual fidelity, you should always fill the entire square with your design, even if that is a solid color.
