- (BREAKING change) Pather.mpath no longer wraps the whole bus into a
container, since this has no equivalent in RenderPather. Possible this
functionality will return in the future
- Removed `tool_port_names` arg from Pather functions
- In general RenderPather should be much closer to Pather now
In order to make layouts more reproducible
Also add pattern.sort() and file.utils.preflight_check()
optionally don't sort elements
elements aren't re-ordered that often, sorting them is slow, and the
sort criteria are arbitrary, so we might want to only sort stuff by name
Since Pattern has ports already, these should live in Pattern and get
wrapped elsewhere. Builder becomes a context-holder (holding .library
and .dead) and some code duplication goes away.
