Optimize Vector Graphics Rendering

[pcolton]

There are probably some opportunities to optimize our vector graphics rendering. This ticket is here to capture some thoughts that will need further research. That research should give us an idea of the best approach we can use to optimize rendering while allowing good flexibility to our end users allowing them to modify and augment our rendering:

• GPU-based rendering - Loop-Blinn - http://research.microsoft.com/en-us/um/people/cloop/loopblinn05.pdf
• GPU-based compositing
• GCD to render individual shapes in a scene, or maybe parallel rendering of scenes
• Convert scene to an array of drawing commands - possibly cache this instead of the scene
• May be able to utilize CAShapeLayers

I wrote QuickSVG which is 100% backed by CAShapeLayers... It's been a fantastic foundation with UIBezierPath to enable very flexible and native translations.

@MattNewberry Where did your QuickSVG go? Would love to have a look. I have an SVG engine to by the way: https://github.com/eonist/swift-utils/tree/master/geom/svg
