Higher-quality cursors with a shadow to make them visible on light backgrounds.

Browse Source 
Same look as in 760606d except for the linking book, which got a slight
curvature on the pages (inspired by Deledrius' one, 99bda8c).

The SVG is hand-tweaked to work around some differences in rendering between
rsvg and Inkscape. I hope editing it in Inkscape again won't break the tweaks,
check the diff closely if you do!

Effects (blurred shadows) appear to be clipped to the SVG viewport by rsvg,
which is why drawing the whole SVG shifted for the book cursors no longer
works and we shift individual layers inside the SVG instead.
