Modify properties of an element in a theme object
Define aesthetic mappings from strings, or quoted calls and formulas.
Given a character vector, create a set of identity mappings
Colour related aesthetics: colour, fill and alpha
Differentiation related aesthetics: linetype, size, shape
Position related aesthetics: x, y, xmin, xmax, ymin, ymax, xend, yend
