The results are checked for intersection in the main update function, and then it crashes because the main function doesn't expect per-extruder disallowed areas yet from the rest.

This computes the disallowed areas of the machine, the disallowed border and the prime tower per extruder. The prime locations are not yet calculated per extruder, but I'd like to extract it to a function before I try that.

This way we can offset it with the nozzle offset and it would still cover all the way to the edge. The disallowed areas are clipped to the build volume anyway.

This function is named as if it could later include other printed pieces, but it is meant to only include pieces that have normal bed adhesion, so not the prime locations.

It's much easier to create, more obvious code, and better approximates the area that we seek to use for our prime location.

The check for collisions is only at the end, and after that it adds the polygon itself. We should keep the code closer together to make it more readable.

Because we have 'areas', 'disallowed_areas', 'self._disallowed_areas', 'disallowed_polygons', and so on. This should reduce the confusion a bit.

This is not used, unless you take multi-threading into account. In that case though, the actual disallowed areas are only updated at the end of this function, and the _has_errors variable is updated right before then as well, so this way the variable is in an invalid state for a smaller amount of time.

These disallowed areas will have to move or get duplicated according to which nozzles are used. Eventually we'll want to compute these with their Minkowski additions only when needed (the skirt size changes), not when the used extruders change. This is also part of an effort to make this disallowed area computation a bit better structured. The behaviour should be the same.

These are the extruders that are being used by the scene if it would currently be printed. You can ask the extruder stacks for stuff like the nozzle offset. This way we can determine the disallowed areas per extruder.
