ggsave can create directories

Code
  ggsave(path, p)
Condition
  Error in `ggsave()`:
  ! Cannot find directory 'PATH'
  i Please supply an existing directory or use `create.dir = TRUE`.

ggsave warns about empty or multiple filenames

Code
  x <- suppressMessages(ggsave(c(file1, file2), plot))
Condition
  Warning in `ggsave()`:
  `filename` must have length 1, not 2.
  ! Only the first,'PATH', will be used.

Code
  ggsave(character(), plot)
Condition
  Error in `ggsave()`:
  ! `filename` must be a single string, not an empty character vector.

ggsave fails informatively for no-extension filenames

Code
  ggsave(tempfile(), plot)
Condition
  Error in `ggsave()`:
  ! Can't save to PATH
  i Either supply `filename` with a file extension or supply `device`.

warned about large plot unless limitsize = FALSE

Code
  plot_dim(c(50, 50))
Condition
  Error:
  ! Dimensions exceed 50 inches (`height` and `width` are specified in inches not pixels).
  i If you're sure you want a plot that big, use `limitsize = FALSE`.

Code
  plot_dim(c(15000, 15000), units = "px")
Condition
  Error:
  ! Dimensions exceed 50 inches (`height` and `width` are specified in pixels).
  i If you're sure you want a plot that big, use `limitsize = FALSE`.

unknown device triggers error

`device` must be a string, function or `NULL`, not the number 1.

Code
  validate_device("xyz")
Condition
  Error:
  ! Unknown graphics device "xyz"

Code
  validate_device(NULL, "test.xyz")

  Error:
  ! Unknown graphics device "xyz"
