Add an example that renders a simple fractal

This works at resolutions where simplification is significantly reducing the number of points in the line.  At high resolutions, navigation becomes unresponsive.  Limiting draw instructions to a replay group's extent will fix this.
Keep track of max extent for replay
Determining coordinate relationship to extent
Testing segment intersection with extent

If needed, this function can be modified to take two additional coorinates that will be set to the intersection points.
Skip coordinates that don't affect the rendered extent

Segments that intersect the replay group's extent are drawn.  Any segment that represents a change in coordinate-extent relationship is drawn.  This maintains the left/right relationship (or cross product) between points in the rendered extent and every rendered segment.

Still left undone: clip the replay group's rendering to the max extent.

Explicit box model definition for box model dependent sizing

The zoom in/out tooltips are clipped when a css reset sets the
box-sizing to anything other than content-box. This breaks the
sizing of these tooltips, because they rely on content-box
sizing. This issue can e.g. be seen when using a bootstrap 3.x
