```
The former declares the directions we want to bind in, where `dir_x` can be one of `left`, `right`, or `both`; and `dir_y` can be one of `up`, `down`, or `both`.
Again, key-level declaration means that both of these should be specified in the `points` section, benefiting from the same extension process every key-level setting does.
The former declares the directions we want to bind in, where `dir_x` can be one of `left`, `right`, `both` or `neither`; and `dir_y` can be one of `up`, `down`, `both` or `neither`.
(If left empty, `neither` will be assumed.)
The latter declares how much we want to bind, i.e., the amount of overlap we want in that direction to make sure that we can reach the neighbor (`num` applies to all directions, `num_x` horizontally, `num_y` vertically, and the t/r/b/l versions to top/right/bottom/left, respectively).
If it's a one-piece design, we also need to "glue" the halves together (or we might want to leave some extra space for the controller on the inner side for splits).

Here, `percent` means the y coordinate along the centerline (going from the top intersection to the bottom intersection), and `width` means the offset on the x axis.
If this is somehow _still_ insufficient (or there were problems with the binding phase), we can specify additional primitive shapes under the `extra` key (similarly to how we would use them in the exports; see below).
These are then added to what we have so far to finish out the glue.

- `side: left | right` : the side we want
- `glue` : just the glue, but the "ideal" version of it. This means that instead of the `glue` we defined above, we get `all` - `left` - `right`, so the _exact_ middle piece we would have needed to glue everything together. Parameters:
- everything we could specify for `all` (since those are needed for the calculation)
- `side: left | right | both # default = both)` : optionally, we could choose only one side of the glue as well
- `raw: boolean # default = false)` : optionally, we could choose to get the "raw" (i.e., the non-idealized) glue as well

Operations are performed in order, and the resulting shape is exported as an output.

Additionally, it is going to be available to further export declarations (using the `ref` type) under the name specified (`my_name`, in this case).
If we only want to use it as a building block for further exports, we can start the name with an underscore (e.g., `_my_name`) to prevent it from being actually exported.
