Remove html5slider #47
 Ability to set default input values on any effect as an option #59
 - with unit test
Added Color Select effect
Vertex shader in Color Select needs to use standard position calculations
Fixed broken scanlines effect
Changed TV Glitch time to be based on seconds, not milliseconds

This will break existing code. Trying to standardize this across effects.
Simplex works on seconds, and it makes more sense this way since a) it's
easier to think about, b) video currentTime is in seconds and c) some
weird noise functions go a bit crazy with very, very high numbers.
Added source plugin for THREE.WebGLRenderTarget, with example
Removed unnecessary
Update Source node when src changes #63
Much better unit test for #63
- no render required
- make sure resize event fires, and only once
- works without WebGL
Fix: Changing image source now works when new image is the same size #63
Included three.js so example works
Fix script inclusions in index.html
- remove uncommitted pixelate effect
- add freeze effect
- remove unused color picker script
Allow effects to become "ready" even if unneeded sources are not ready
- simplified `setReady` and `setUnready` methods on EffectNode
- should make compositions load more gracefully, allowing for some sources to be loaded a little bit late
- unit test
- blend
- displacement
- fader
- freeze
- layers
- select
- split
Don't need to resize Select effect and all subsequent nodes on every draw
Added Fast Approximate Anti-Aliasing (FXAA) effect
- Added optional FXAA pass to Three.js example
- optimized Three.js example by removing redundant blend nodes
Bug Fix: incorrect value from checkboxes
Auto scaling for Camera Shake #44
Removed centerX and centerY from camera shake. They don't make sense
anymore, because there's no good way to auto-scale when re-centered.
If you want to re-center for rotation, it's best to use 2d transform
nodes before and after the camera shake.
Camera Shake has preScale = 1 by default
- Drunk demo no longer needs scale node, can just use auto scale in camera shake
Callback function in `go` provides time as first parameter
- Examples updated to use it
- passed from requestAnimationFrame, high-precision time in milliseconds
