gggenes 0.7.0

New features

• geom_subgene_arrow() and geom_subgene_label() now support polar coordinates.

Minor improvements and fixes

• gggenes now validates layer input and reports problems with clearer, more consistent error messages (#91, #92).
• gggenes now transforms data coordinates once per panel rather than once per glyph, speeding up the rendering of layers with many glyphs (#113).
• The rendering pipeline is refactored to share more logic across geoms (#93, #109).
• Grid drawing now uses NPC rather than native coordinates internally (#94).
• The package documentation is updated throughout, and the README now presents polar-coordinate drawing with coord_polar() as a supported feature rather than as experimental (#115, #116, #117, #122).
• The declared dependency floors are now honest: ggplot2 (>= 3.4.0) for the linewidth aesthetic, rlang (>= 1.0.0) for rlang::caller_arg(), and ggfittext (>= 0.9.0) for polar-coordinate text fitting (#107).
• geom_feature() and geom_terminator() now document that their linewidth is expressed in points rather than millimetres, unlike geom_gene_arrow() and the ggplot2 convention; this inconsistency will be reconciled when these geoms are superseded in gggenes 1.0.0 (#121).
• geom_feature_label() now draws when the forward aesthetic is not mapped (#98).
• geom_feature_label() now sizes the label box of a forward = TRUE feature to the full panel in polar coordinates, spanning to the theta edge at 2 * pi rather than to 1 radian (#112).
• geom_feature_label() and geom_terminator_label() now draw on the opposite side of the molecule with a negative feature_height or terminator_height, and their height-parameter documentation is clarified (#90, #99).
• geom_gene_arrow(), geom_subgene_arrow(), geom_feature(), and geom_terminator() now handle the deprecated size aesthetic consistently, each emitting a single deprecation warning (#102).
• geom_gene_arrow() and geom_subgene_arrow() legend keys now apply alpha to the outline colour as well as the fill, matching the drawn geoms (#101).
• geom_gene_label() and geom_subgene_label() register the align parameter explicitly (#104).
• geom_subgene_label() now draws in polar coordinates with only its required aesthetics mapped, without also needing xmin/xmax (#106).
• Polar segmentation now keeps the endpoint of a very short edge, so a glyph edge shorter than one segment is drawn rather than collapsing to a single point (#114).
• make_alignment_dummies() now gives a more informative error when on is absent from the mapped id column (#119).

gggenes 0.6.0

Major changes
