f20db28901 Align layer canvas to the left 
So that the position is not affected by the `text-align` css rule.

2b36445ecc 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.

f25a16d90c Webgl helper / rework create texture utils 
Now only one util is available: `createTexture`, which
is tested and allows binding an image and reusing an existing texture.

2412fe0211 Webgl / remove handling of element_index_uint extension 
From now on we will assume this extension is always enabled.

An error message have been added in the unlikely scenario of a lack
of support.

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.

3e2e45ce6d Webgl helper / add the possibility to use transforms as custom uniforms 
These will be translated into 4x4 matrices in GLSL.

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.

2367fbb1ea Webgl / do not enable missing attributes 
Some expected attributes might not end up in the compiled shader. In this case, skip calling enableVertexAttrib

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.
