Render canvas line plot with multiple styles

[waltonseymour]

Enables the ability for canvas lineDrawer to utilize different styles in the same plot. This is especially useful for changing opacity/stroke for segments along a plot. When drawing between two points that produce different styles, it chooses the first style arbitrarily.

Hey thanks for this contribution. I'm still reviewing the performance implications of the new iteration in the line renderer. At high scale, this can have a significant impact on perf. Thanks for your patience
