DiagramImageItem::fromXml() read the size attribute with a plain toDouble(). A picture whose size was missing or not a number got size 0, so it was invisible on the folio, left out of the SVG export, and a resave wrote size="0" back, which then stayed 0 on every load. "nan" was kept and written back as such. The <transform> child, which newer files carry, already defaults its scale to 1. Read the size with an ok flag and use 1, the size a picture is added with, when it is missing, not a number, not finite, or 0. No file-format change for usable sizes. A picture that an earlier save left at size="0" shows again, at size 1, after this change. Tests: tst_imagemissingsize runs the binary's --resave and --export-svg on a fixture with six small pictures: size missing, "0", "nan", "big", "0.5" and "2". The first four fail on master (saved as 0, 0, nan, 0) and the export draws only 3 of the 6 pictures there.
