2032967 - Support merging an image file into a PDF

We now support merging a PDF into another PDF, we can also easily support merging an image into a PDF (so the image becomes a new page in the PDF).

There are few questions we need to answer before starting:

• what will be the page dimensions ?
  • images one;
  • pdf ones: if all the pages in the pdf are A4 then it probably make sense to use A4 too, but what does happen when the pdf has some pages with different dimensions.
• do we want to add some margins ?
• do we want to apply a compression ? JPEG compression is destructive so it's worth asking. We can use a non-destructive compression. Images can be very big sometimes (for example when coming from a mobile).

Anything else ?

The UI will mainly depends on the answers to these questions.

We could start with the choices that are the simplest to implement:

• always pdf ones, matching the most frequent page type in the pdf
• same orientation as the most frequent page orientation in the pdf
• no margins
• always JPEG compression (but I imagine most images people will add are JPEG already)

And then gather feedback from users to figure out if they want a small dialog to choose options.

I am keeping the relnote-firefox? flag set until we include this note in our final 153 release notes, thanks.
