Don't rasterize linked SVG with <image>

Originator: NO

cool, didn't realise support for importing SVG files using image tags had
been (sort of) fixed already
[ 1573020 ] Use the <image> tag to import another SVG file
https://sourceforge.net/tracker/index.php?func=detail&aid=1573020&group_id=93438&atid=604309

the bug Horkana refers to above is now at bug 171544 in launchpad.

As a side note, the rasterization seems to be at 90dpi of the *source* svg (i.e. the file that is being imported).

As far as I can tell, Inkscape (stable and trunk) does not use its internal renderer for the content of an <image> tag linking to an SVG file, but librsvg:

For a test, create a small file with a short flowed text, and link it in a second file via <image> tag: the flowed text will be rendered as black box (because it is an unsupported feature in any other SVG renderer except Inkscape).

Related reports:
Bug #168244 “[win32] image tag does not find SVG source”:

Bug #461842 “Image filter effect using path has low resolution”:
<https://bugs.launchpad.net/inkscape/+bug/461842>

This appears to be added in Inkscape 0.48. E.g. I was able to import an Inkscape SVG into another document and edit the SVG sub-elements separately.

Brylie: what you did was importing the document, not linking it: in your case the contents of an svg file is embedded in another).
The problem is not fixed in 0.48.

This is happening with any way of using another SVG document from the main SVG document.

For example, consider this example:
https://rawgit.com/tanty/design-hodgepodge/master/svg/filter/igalia-feblend-feimage-explicit.svg

On it, we define another embedded SVG document in the "defs" part of the main document to use as graphic source for a filter.

Opening with Inkscape we can see how the embedded SVG has been rasterized :(

This bug is marked as a duplicate of bug #168244. This problem is still happening, and is a big problem for me (Trying to link to an external svg file causes the message in Inkscape "Link not found") - is there any new info I could provide to get work started to fix this. I am using Inkscape ver 0.92 on a windows 7 machine.

When I tried it just now, in Inkscape master, I got no error message, but it embedded a masked raster version with a black background instead of transparency (hence the mask) of the SVG into the pdf.
