3D Rendering

[keithsw1111]

I have pushed the 3DR branch with an implementation of true 3D effect rendering. It is early days right now with only 2 models supported (cube and custom) and only one effect truly rendering in 3D ... shockwave.

Most effects wont be that interesting so i dont necessarily think we need to rework them all ... but a few could be interesting like fireworks, meteors (like explode), circles, life, lightning, lines, marquee, (maybe morph), music, pinwheel, plasma, ripple, shape, vu meter, sketch, snowflakes, tendril, tree.

Also 3D transitions would be interesting.

I would also like model groups to support a 3D buffer allowing you to use these 3D rendering effects to work on a whole house across all dimensions.

In order to render in 3D you have to choose that buffer. But because xLights was pretty much hardwired as 2D ... this resulted in a lot of change so there is a fair chance i broke some things along the way.

Feel free to contribute to the branch and we can merge at an appropriate time ... likely just after christmas (I think it is a bit late for this to be released this year).
