8566cfc227 Webgl points / get back the instructions array from the worker 
This means we won't have to recreate a binary buffer (through a typed array)
on every `rebuildBuffer` call.

65be907095 Webgl points / shifts the buffer write logic in a worker 
The worker receives a transferable array of instructions
and sends back two transferable arrays (vertex and index buffer).
The projection transform is also sent so that when the main thread
receives the buffers from the worker it also knows which projection to
apply when rendering the geometries.

532b8194b1 Webgl points / use the new typed-array based utils for buffers 
`rebuildBuffer` is still a very CPU intensive task and is blocking the
main thread.

5d2b7fe4bb Webgl points / use the helper ton compute the projection transform 
The `WebGLHelper` class now provides a `makeProjectionTransform` method
that updates a transform to match the projection for a given frame state.

This also means that the WebGLHelper does not set the projection matrix
uniform anymore, this is the responsibility of the renderer as
the rendered coordinates will not be in world space from now on.

c6a859d1ed Webgl / clarify premultiplied alpha handling 
By default, alpha premultiplying should be done by the initial rendering
(eg quads) and not the final post processing pass.

The default post processing pass expects premultiplied color values and
will not do this operation itself.

The Webgl points layer renderer has also been optimized accordingly,
giving out much better performance.

f177a2bcd5 Simple handling of layer opacity in webgl points layer 
Now the layer opacity is simply handled by a CSS property on the layer DOM element. As such it does not have to be
taken into account in shaders.

6b82cf0b84 Simplified the API of WebGLHelper 
Now the shader and program caches are simply arrays of native WebGL created objects.
The WebGLHelper simply takes the sources of the frag and vert shader and produces a program.

This removes 2 classes & reduces the general verbosity of the API.

Also a `getShaderCompilationErrors` was added on `WebGLHelper` to help debug GLSL errors.
