%description
Algebra of operations for blending, copying, adjusting, and compositing
layers in 'ggplot2'. Supports copying and adjusting the aesthetics or
parameters of an existing layer, partitioning a layer into multiple pieces
for re-composition, applying affine transformations to layers, and
combining layers (or partitions of layers) using blend modes (including
commutative blend modes, like multiply and darken). Blend mode support is
particularly useful for creating plots with overlapping groups where the
layer drawing order does not change the output; see Kindlmann and
Scheidegger (2014) <doi:10.1109/TVCG.2014.2346325>.
