Hello, again.

I thought this and little Googling about this image format .

There will be the way to add additional condition that recognize types of
system(that is, 'system-type).

But I can't find the point of putting effort into displaying SVG images
when image type 'svg' isn't available, and when we can use other image
formats instead.

(for me, these splash.* images are almost looks same).

I attach the patch.
How about this?

Thanks,
