Overview

Emits the small "folded paper" classifier-type icon at the top-right corner of an element box. EA renders this when the element's style does NOT set HideIcon=1.

The icon is two <path> elements:

1. Outer outline (closed): a 9×11 rectangle with the
 top-right corner "folded" (a 3×4 triangular cut).
2. Folded corner detail (open): the L-shape indicating
 the fold.

Style:

- Outer:    fill=#DCF8F0, stroke=#577AC1
- Corner:   fill=transparent, stroke=#577AC1
- stroke-width=1, stroke-linecap=square, linejoin=bevel
