Proposed changes for V5.0

SceneJS V5.0 will contain some API changes that will break backwards compatibility, along with a bunch of optimizations that worked out well for xeoEngine.

Arrays instead of vectors

Use arrays for node attributes such as positions and colors, instead of objects. Eg instead of

{x:1, y:2, z:3}

we would have

[1,2,3]

Tidy up event management

• See https://github.com/xeolabs/scenejs/issues/332

Optimizations

• Use numeric state IDs within the renderer core for faster state tracking.

Task queue with per-frame budget

• Asynch tasks, eg. geometry generation, node creation etc, will be pushed as tasks to a global queue which will be pumped on each frame, to try to keep the FPS stable.

Node component changes

• Node attribute accessors will be properties that fire correspondingly-named change events when updated, similar to xeoEngine component attributes.
