For images smaller than the viewport at 100% zoom, Gwenview allows to
scale up the image to Fit the window if Enlarge smaller images
is checked in the configuration dialog. So far this only worked for
raster-based images, but not for SVGs.
mEnlargeSmallerImages is meant to be handled by the abstract base
class AbstractImageView, however when f00cef3c0 moved code over there
from RasterImageView, it was missed to also adapt SvgImageView. This
can be fixed by implementing the missing function.
In addition, a left-over bool is removed.
