Olivier Guyot a6f65df8c4 View / add a resolveConstraints method to end interactions 
This will help making sure that the view will come back to a "rested" state
once the interactions are over.

Interactions no longer need to handle the animation back to a rested state,
they simply call `endInteraction` with the desired duration and direction.

Olivier Guyot 1c5fd62e43 View / refactor how zoom and resolution are computed 
This commit aims to simplify the computation of zoom and resolution in the
View class.

Previously zoom levels and resolution computations were mixed in different places,
ie resolution constraints, initial values, etc.

Now the View class only has the `getZoomForResolution` and `getResolutionForZoom`
methods to convert from one system to another.

Other than that, most computations use the resolution system internally.

The `constrainResolution` method also does not exist anymore, and is replaced
by `getValidResolution` and `getValidZoomLevel` public methods.

Olivier Guyot 1f379a06a4 View / add support for viewport extent constraint 
This introduces a breaking change:

The `extent` view option now constrains the whole viewport and not just the
view center.
The option `constrainOnlyCenter` was added to keep the previous behaviour.

Constraining the whole viewport and not only the view center means
that the center and resolution constraints must be applied with a knowledge of
the viewport size.

Olivier Guyot e6c4b2ffd1 View / make the constrainResolution function private 
Other classes should not need to worry about constraining the resolution
or not, as the View will eventually do this on its own.

Olivier Guyot 3c1e3779e2 View / add a method to compute a valid zoom level 
The `getValidZoomLevel` apply the current resolution constraint to return
a value that is guaranteed valid.

This is used for interactions & controls which need a target value to work:
the +/- buttons, the zoom clider, the dragbox zoom and the mouse wheel zoom.

Olivier Guyot 1cb934dbe3 View / implement intermediate values for center/rot/res 
The view now has targetCenter, targetRotation and targetResolution members.

These hold the new values given by set* methods. The actual view parameters are then changed by
calling `applyParameters_`.

Olivier Guyot 2c4a959e55 Generally fixed the webgl heatmap layer 
Things done:
- stay closer to the original rendering in canvas
- get rid of the intermediary blur step
- use the new callbacks in the webgl points renderer
- premultiply alpha in the last postprocessing step

Olivier Guyot 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.

Olivier Guyot a6989af00a Webgl points layer / added callbacks for attributes 
Now opacity, rotateWithView and tex coords can be set with callbacks per feature.

jahow 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.
