Tile Based Deferred Rendering upon WebGL2 API

[Danielmelody]

Deferred rendering, is a multi-lighting algorithm which is mostly used in modern rendering system.Techniques needed for deferred rendering are based on OpenGL ES 3.0+ and upon.

The WebGL API 1.0 provide WEBGL_draw_buffers as an extension and promoted to core in WebGL API 2.0 to support deferred rendering. So to add this feature, there are several works to do:

• Implement g-buffer
• Add tiled geometry
• Implement tiled light pass
• Multi-materials support
• Transparency material support
• Add examples for performance and unit test cases

I believe those will be amazing

Well, I just came across a strange problem, I cannot get perfect rendering result when rendering more than 20 lights, The tiles keep twinkle when update frame, just like this

I feel it is the precision problem here, now I 'm searching others implementation to solve it, I really need some help.

Fixing is on progress
