Answer 1

After a good discussion w/ -dev I have some clarification on how to handle the data for bottom vision and how to use that data elsewhere. Instead of the current system where we have an outline and footprint that are not well defined, we can simplify down to a simple width and height of the package and a list of pads and their sizes.

This is similar to the current footprint, just adding the width and height. It probably makes sense to just put these attributes directly on package and dump the footprint and outline classes. This will make the package editor much easier, too, as it can just be a table of pad definitions along with the part body dimensions.

Once these exist, it would be useful to add back the visualization that was removed in 198821d3bb8f7b8482da934867170759d37995fe but make it something you turn on and off instead of always being on when selecting a placement.
