[librsvg: 6/11] Rename the "affine" field in pattern structs to "transform"

[Federico Mena Quintero <federico src gnome org>]

commit 8cc0d6769efaf1e3504079f4222bee2250249c24
Author: Federico Mena Quintero <federico gnome org>
Date:   Tue Dec 1 10:14:32 2020 -0600

    Rename the "affine" field in pattern structs to "transform"
    
    The corresponding attribute in <pattern> is patternTransform, after all.
