Georgian/Armenian fonts for code

To read and write code that contains Georgian and/or Armenian characters, a combination of any preferred typeface with fallback DejaVu Sans Mono can be used.

For example, in VS Code settings.json:

{
    "editor.fontFamily": "'JetBrains Mono', 'DejaVu Sans Mono'"
}

// This is more along the style of a really good CGA arcade monitor.
// With RGB inputs instead of NTSC.
// The shadow mask example has the mask rotated 90 degrees for less chromatic aberration.
//
// Left it unoptimized to show the theory behind the algorithm.
