width/height support in geom-rastor #350
Description
Not sure if this is necessary, but will be useful.
df1 <- data.frame(x = c(1, 1, 2, 2), y = c(1, 2, 1, 2), z = 1:4)
df2 <- data.frame(x = 1:3, y = 1, z = 1:3)
df3 <- data.frame(y = 1:3, x = 1, z = 1:3)
df4 <- data.frame(x = 1:3, y = 1:3, z = 1:3)

p <- ggplot(d, aes(x, y, fill = z))
