SVG Slides Backend

[Kristian Høgsberg <krh redhat com>]

Hi,

We've been using a new evince backend to show our slides during a couple 
of talks we've given on the Fedora Rendering Project [1].  The slides 
themselves are just SVG files and they way the backend works is that it 
reads an index file and uses that to figure which SVG files to load in 
which order.  The index file is just a simple XMl file:

  <?xml version="1.0"?>
  <svgslides-index xmlns="http://www.svgslides.org/svgslides-index0.1";
                   title="test">
    <slide filename="test-001.svg" title="This is a slide"/>
    <slide filename="test-002.svg" title="Bigblue Theme"/>
    <slide filename="test-003.svg" title="Back to normal"/>
  </svgslides-index>

The SVG rendering is done using cairo: the main content area is rendered 
with the Xlib backend using Render, the thumbnails are rendered with the 
image (in-memory pixbuf) backend.  The SVG parsing is done using libsvg 
and libsvg-cairo, available from the cairo cvs repository on 
freedesktop.org.  In cairo cvs there is also a small python script that 
Carl Worth wrote to parse some minimal html-like slide markup and an SVG 
template and from that generate an index file and svg files suitable for 
use with this evince backend [2].

I don't know if this is something you want to add to evince, but here's 
the patch, feel free to use it!

cheers,
Kristian
