    EogPrintPreview: Fix possible integer overflow
    
    Import a fix into code copied from GDK which was susceptible to a possible
    integer overflow (cf. CVE-2013-7447). This is practically the corresponding
    fix from GDK. The code in eog however should only work with images too small
    to trigger this integer overflow.
