Fix the PDF format with extra line and put 2 images per page

[julbrs]

Hello

Some remarks:

• 2 images per pages: I am just doing the math and realized than 2 * 14cm is less than the 29.7cm of A4 paper :) that's ok !! (for letter it is 8.5' x 11' and 11 inches is a bit less than 28cm so maybe not enough ?)
• regarding the imports: I use to work with the DompdfWrapper that is a service on top of Dompdf dedicated to Symfony. The import in composer is core23/dompdf-bundle. If you switch to use directly Dompdf object then I suggest to remove the DompdfWrapper import and use the dompdf package (dompdf/dompdf) directly instead of the bundle. (but I prefer using the wrapper/bundle instead of the dompdf direclty, but I don't know why exactly 😄 )

Thanks !

Hi, Regarding formats, yes we will have to define another format for printed version (when a user will be able to choose between them :)). Regarding the import, I used dom directly because I didn't know how to change the settings (i.e. A4 landing space) but if there is an option to do it in wrapper I will be happy to use it :)

Hello

I have added a small commit to use the wrapper and set the defaultOrientation to "paysage". The PR is OK for me I let you merge if my commit is OK for you ;)
