Adding handlbars to spline nodes

[joshusama]

What's the problem this feature will solve?
Allow much easier manipulation of spline curves

Describe the solution you'd like
When one clicks on a spline node, handlebar vectors appear that have nodes which can change the curve of the line on one side of the original node or the other. Basically, like Illustrator

I drop 3 nodes in a very small spline and the angle of the line as default is perhaps not as acute as it needs to be. Sometimes adding a node to these small polygons is difficult (for some reason) or can tangle (other known issue). If one could work with the nodes that do exist and just change the angle of their operation, there's less chaos from adding more nodes or frustration when it wont allow them to be added reliably because the polygon is small or new nodes are placed in unexpected places.

Alternative Solutions
Just try to add more nodes and guess where to best move them around to get the desired shape.

With illustrative work involving Adobe for example, it's general practice to drop as few nodes as possible and focus on manipulation of handlebars. Easier for later editing, easier to adjust in initial drawing.
