If you use colour = NA, it doesn't work with a colour aesthetic set - dodging still stuffs up

Premise: polygons should default to linewidth of 0 and alpha of 1:

• size is not distorted
• they will sit adjacently nicely
• the colour will be aligned with points/lines

alpha_area = 1,
alpha_bar = 1,
alpha_polygon = 1,
alpha_rect = 1,
alpha_tile = 1,
alpha_violin = 1,
alpha_density = 1,

linewidth_area = 0,
linewidth = 0,
linewidth_polygon = 0,
linewidth_rect = 0,
linewidth_tile = 0,
linewidth_density = 0,

linewidth_ribbon = 0,
alpha_ribbon = 1,

Alpha 1, except:
alpha_boxplot = 0.33,
alpha_crossbar = 0.33,
alpha_smooth = 0.33,
alpha_label = 0.05,
