gggenes 0.6.0.9007

Breaking changes

• linewidth in geom_feature() and geom_terminator() is now expressed in millimetres, not points, for consistency with geom_gene_arrow() as well as ggplot2 convention. This will have a negligible effect on plots that use the default linewidth values for these geoms, but will cause a significant visual change where linewidth is set manually (#89)

Minor changes

• Clarify feature_height and terminator_height parameter documentation in label geoms (#90)
• Add polar coordinate support for geom_subgene_arrow() and geom_subgene_label()
• Add developer vignette documenting coordinate transformation internals
• Consolidate coordinate transformation logic into compose_grob() interface
• Add comprehensive input validation (#91)
• Improve error messages (#92)
• Minor internal refactoring (#93)
• Standardise on use of NPC (not native) grid coordinates internally (#94)
