Scale a pts_tbl into a viewport

scale_into_viewport(
  tbl,
  xc_ = 0, yc_ = 0,
  side_ = 1,
  x_ = x, y_ = y,
  use_bounding_box = TRUE,
  keep_bounding = FALSE
)

`tbl`	[tibble], tibble of points
`xc_`	[numeric], length 1, x center of viewport
`yc_`	[numeric], length 1, y center of viewport
`side_`	[numeric], length 1, nonnegative, the width of the side of the viewport
`x_`	[symbol], length 1, variable name to use as `x` in `tbl`
`y_`	[symbol], length 1, variable name to use as `y` in `tbl`
`use_bounding_box`	[logical], length 1, default `TRUE`, if `FALSE` rotate3 does not use bounding box points to make computations default behavior is to use bounding box points to make computations
`keep_bounding`	[logical], length 1, default `TRUE`, if `FALSE` does not rbind the bounding box back after computation default behavior is to use bounding box points to make computations

      [{type}]

tibble with values
x x coordinate of viewport
y y coordinate of viewport
z z coordinate of viewport
face is point part of "front", "back", "left", "right", "bottom" or "top" face
tb is point on "top", "middle", "bottom" side of face
rl is point on "right", "middle", "left" side of face
