The color names are more intuitive. And if we want to support pattern strokes or fills, we'll need additional proerties to represent other pattern properties.
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.
To avoid surprises, we configure everything that is a WMS GetMap
request parameter in the params object, and not as direct
configuration option. This affects the VERSION and TRANSPARENT
params.
Previously, a lookup object containing start indexes was also used. This allowed us to remove arrays of vertices and properly update the start indexes for remaining coordinate values. In order to provide callers with stable identifiers and to work with arrays of integers alone, we cannot support a remove method. I think this is worth revisiting. Even if the array length cannot be changed in WebGL, we don't need to also impose the restriction outside. Instead, the WebGL renderer could be notified when array sizes change and update itself accordingly. I think there is more value in providing geometries with stable identifiers.
This common structure is used to store vertices for all geometry types. A slight optimization could be made by creating yet another structure to store point vertices - since these don't need to have a counts array (always 1). Creating a new structure would mean saving memory at the expense of more lib code to transport. The coordinate value lookups are not negatively impacted by using the same structure for points and higher order geometries. Since the first change above goes against my instincts, I'm not making this second change (to add another structure for shared point vertices).

This change adds a lot of flexibility to working with tile
layers: Sources where the server projection or tile grid do not
matter can now be constructed without specifying a projection or
tile grid.
The tileUrlFunction/imageUrlFunction now also creates updated
URLs when the params of the layer change, so things like
mergeNewParams in ol2 will be possible.
A nice side effect of this whole change is that there is no more
duplicated code between tiled and single image WMS layers.
While I was at it, I also fixed a WMS 1.1.1 axis order issue
and incorrect STYLES params (STYLES=& instead of STYLES&).
