This follows the convention in the Closure Library of providing either namespace objects (where the property starts with a lowercase letter), constructors (where the property starts with an uppercase letter), or enums (all uppercase properties, only one instance of this in the closure library).
Currently the animation functions share the same module, namely ol.animation. We do differently for ol.control.defaults and ol.interaction.defaults, with ol.control.defaults and ol.interaction.defaults module. This commit replaces the ol.animation module by four modules, one for each animation function.
This makes things more consistent, and will make it possible to use the @exportFunction annotation for the exporting of the animation functions.
The following functions are renamed:
getTransform -> getTransformForProjections
getTransformFromCodes -> getTransform
transform -> transformWithProjections
transformWithCodes -> transform
With this change, the faster functions that avoid projection look-up
have longer names and are used internally, whereas the slower but
friendlier short name functions are available for users.
