Basically my problem is that inkscape only seems to support loading, and rendering an SVG in the main UI thread - anything else causes it to die. But also only the main thread can handle Windows messages. So I can get the SVG to render into my preview pane, but during rendering, because the rendering occurs in the main thread, the UI locks up until the rendering is complete. Given that calling sp_document_new to load the file blocks for 100-600ms, and rendering takes 200-1500ms for practical SVGs, the code that I have can hardly be called an upgrade!
Perhaps you could use the cairo renderer for the previews, since we already include cairo, so you'll only need to include some bits from rsvg (or whatever the cairo-based svg viewer is called). This can be done in a different thread and I suspect would be generally faster than Inkscape renderer anway.
