Galette

Several issues exists:
- logo size is wrong if image is landscape, works a bit better with a portrait one,
- text overriding exists,
- slogan is cropped instead of being resized.

As a workaround, it is possible to use the old file:
https://github.com/galette/galette/blob/1.0.4/galette/lib/Galette/IO/PdfMembersCards.php

A quickfix would be to revert the new card code.
