Shader builder / add logic for transforming a style into shader params
...
This was previously handled by the WebGLPointsLayer class, but is now
externalized and tested.

Only a handful of expressions for now, very loosely based on the
mapbox style spec. Also only work on numerical values.

Webgl / Adapt the points renderer to use custom attributes
...
Now most attributes will be custom ones defined by the user of the renderer.
The hit detection is broken for now and still has to be fixed.
Also it is not possible anymore to give a texture to the renderer,
this will have to be fixed as well.

This required adding a `a_index` attribute in the points layer renderer
to be able to make the precomputed shaders to work.

`clearCachedData` is called.

It also allows clearing its content before a new render.

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.

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.

Simple handling of layer opacity in webgl points layer

taken into account in shaders.

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.
