This PR is a follow-up to #250 which makes the browser size equivalent to the page size to make sure figures have correct dimensions and positioning. Although it works well as reported by @ycaokris, it didn't take into account the landscape option which led to badly laid out PDFs.

The fix is to simply swap width and height of the browser size when printing in landscape mode.

Tested with docker image quay.io/plotly/image-exporter:d5d6a741047dc56fa5a63e713725e8fd40bc710e for confined sized snapshot
https://dash-nightly.plotly.host/ddk-manufacture-spc-dashboard/snapshot-1569944213-f1e08e4a?print=true

The outmost container is set to {'width': '11.69in', 'height': '8.23in'} to validate we have same pdf layout for

  1. pageSize {"width":"297000","height":"211000"} as inner key(inside pdf_options), landscape false
  2. pageSize {"width":"297000","height":"211000"} as top-level key, landscape false
  3. pageSize "A4" as inner key, landscape true
  4. pageSize "A4" as outer key, landscape true

Result as follows:

All tests are giving me proper sized snapshot. This means browser size for landscape is swapped for adaptation. Thanks @antoinerg

The only remaining problem which might need me a tweak is height rounding of container size. A standard A4 page orca has returned to me is measured 11.69 in x 8.26 in(as below). However I have to set container size a bit shorter as 8.23 in in order to get all components fit in,

a one-to-one size (by setting container 11.69 x 8.26 will start excluding graphs as like

dash_spc_customized_w_h_container_landscape_A4_false_826inx1169in_A4.pdf

This could be replicated on above container by 1v1 matching pdf size to be ~8.23in x 11.69in

and got

Let me know if we need further test for it. Otherwise everything looks good.
