score: render created using element not ID

The renderer should not have to lookup the element that it should use as a
canvas, it should simply be given one. This is a minor change but it will make
it easier to work with multiple canvases.
readme: minor re-wording
index: removed style element
index: changed svg to div

Using the svg element was the wrong thing to do and cause a clipping issue. The
'canvas' element will be the parent of an SVG element created by Raphael.
Embedding an SVG element inside another SVG element causes some confusion when
it comes to determine the size of the element.

Merge branch 'staging'

These changes are mostly to fix the SVG clipping bug. There were a couple of
parts to this problem. The first is that I was using an SVG element as a
container of the SVG created by Raphael, and this doesn't work very well.
Secondly, the size of the SVG created by Raphael does not seem to respect the
actual size of the path and rectangles in the SVG. I suspect I am doing
something wrong but my workaround for now is to manually calculate the bounding
box and set the SVG element size accordingly.
