SVGs are not resized down to fit on Image: pages. They are rendered at their
normal size, and then placed on the page with the width="800" (or whatever your
setting is) attribute set in the image tag, meaning they are only rescaled by
the browser. This is beacuse mustRender() (Image.php) returns true for SVG,
hoever simply adding "image/SVG" to this list of types that return false in this
function does not fix the problem, as this causes the SVGs to render to the
wrong path.

My hack invovled changing line 171 of ImagePage.php
 from:

  if ( !$this->img->mustRender() 
       && ( $width != $this->img->getWidth() || $height !=
$this->img->getHeight() ) ) {

 to:

  if ( (!$this->img->mustRender() || $this->img->getMimeType() == 'image/svg' )
       && ( $width != $this->img->getWidth() || $height !=
$this->img->getHeight() ) ) {

which solves the problem, but is it a bit ugly.
