* Replace crash with warning when a transform could not be automatically
  re-run
* More sensible default paths for Vamp plugin lookup (at least on Linux and
  OS/X)
* A start to making the y coords for time value layers etc align
* Set sensible y coords for text labels in time instant and value layers
