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.
Instead of working with ol.Coordinate instances, transform functions work with arrays. This is in anticipation of using transform functions to transform large arrays of vertex coordinate values. The ol.projection.transform and ol.projection.transformWithCodes are slightly more convenient functions for dealing with ol.Coordinate instances. Whether we make this more consistent with the use of functions returned by ol.projection.getTransform is up for discussion.
