Allow applying arbitrary transformations to images

[Rodrigodd]

Is your feature request related to a problem? Please describe.

It is not currently supported to add an image with arbitrary transformation, which is needed when trying to rebuild a PDF from the data extracted from another PDF. See #3230.

Describe the solution you'd like

Add a parameter morph to Page.insert_image, similar to the one found in the Shape API. This parameter could also be added to Page.show_pdf_page or to a new method like Shape.insert_image.

Describe alternatives you've considered

There is currently a workaround for this by abusing Page.show_pdf_page, see #3230 (comment).

Additional context

Page.get_image_info already returns a transform of the image, that could be used in the proposed morph parameter.

As mentioned in the Discussions section, I see no way to include this in our near to medium term planning.
So I'm flagging this as "postpone" for now.
