1) Do not setOption('mode',new_mode) on CM if new and old mode are the
same. It triggert **a lot** of calculation of bounding box in the
end.
2) Do **not** select cell when loading the notebook it triggers
**a lot** of CM even that check visible things and so on and so
forth. So add a option to add_cell_at_index not to select it
3) jQuery $.attr has some magics, but has a slight overhead on
real native ELEM.setAttribute DOM method. Seem slight improvement
when loads of PNGs on one page
Any content whose metadata contains an `isolated` tag will be isolated
from the rest of the document.
The current implementation wraps isolated content into an iframe.
When multiple inline SVGs are included in a single document,
they share the same parse tree. Therefore, style collisions and
use id collisions can occur and upset the rendering.
This patch wraps each SVG inside an individual iframe, ensuring
that SVG's declarations do not collide.
(The SVG representation is kept as XML and not converted to a binary
format, so I do not think this approach precludes the use of d3.js)
