Easy.
Now for the trickier part: keys.
There are four ways to set key-related options (again, to minimize the need for repetition):
There are five ways to set key-related options (again, to minimize the need for repetition):
1. at the zone-level
2. at the column-level
3. at the row-level
4. at the key-level
1. at the global-level (affecting all zones)
2. at the zone-level
3. at the column-level
4. at the row-level
5. at the key-level
These "extend" each other in this order so by the time we reach a specific key, every level had an opportunity to modify something.
Note that unlike the overriding for rows, key-related extension is additive.

Lastly, while there are a few key-specific attributes that have special meaning in the context of points (listed below), any key with any data can be specified here.
This can be useful for storing arbitrary meta-info about the keys, or just configuring later stages with key-level parameters.
So, for example, when the outline phase specifies `bind` as a key-level parameter (see below), it means that the global value can be extended just like any other key-level attribute.

`outline` specifies which outline to import onto the xy plane, while `extrude` specifies how much it should be extruded along the z axis.
After that, the object is `translate`d, `rotate`d, and combined with what we have so far according to `op`.
After that, the object is `translate`d, `rotate`d, and combined with what we have so far according to `operation`.
If we only want to use an object as a building block for further objects, we can employ the same "start with an underscore" trick we learned at the outlines section to make it "private".
