Window Placement Icon
These icons are for describing the default layouts for a window manager. I suppose they more generic description would just be a (screen shaped) box within a box. There are some existing icons that somewhat match like `picture-in-picture` and `frame-corners` but they don't form a cohesive collection.

Here are what I designed for my use case, though the mix of filled & outlined might not work for the set. Maybe this would be the filled weight and the outlined weights would use the hashed shading like `square-half`? I based my design on the `frame-corners` icon to get the screen aspect ratio box.

Variants:
- Window Full
- Window North West
- Window North East
- Window South East
- Window South West
- Window East
- Window West
- Window North
- Window South
- Window Detached - I use this to describe windows that aren't snapped to any point and are freely floating.
