Enhance Documentation on merging rotated PDFs

[Lars147]

Explanation

Documentation on the function pdf_page.transfer_rotation_to_content() would be a great benefit. I had a hard time figuring out what I was missing when merging a rotated pdf file.

Here is an example how a documentation PR can look like: #1647

@amaank404 Do you want to improve the documentation?

This is already documented for at least the stamping/watermarking docs.

I beg to differ, I started by reading the API Docs directly. I suppose it would be better if a little reference to this apply function was present. Like a footnote that to actually apply the values to the elements, please look at this function (Important for merging purposes).

I am taking up this issue, I propose to add a reference to the rotate functions of pageobject and transform function of the pageobject. I will do so once I get approval from people here.
