The Vincenty formula can fail to converge for antipodal points (see http://en.wikipedia.org/wiki/Vincenty's_formulae#Nearly_antipodal_points), so those test cases are removed. These tests fail with the latest V8 due to optimization of trig functions with lookup tables. For example, Math.cos(Math.PI / 2) is no longer calculated based on the value of Math.PI / 2 (which is different than the actual value of π / 2). Instead, values close to multiples of π / 2 are determined to be 0 (which is arguably what you want). Previously the tests were relying on very small numbers being returned in this case.
This reverts 4d619d71b1 (see #1527), going back to what we had after e13075f6ff (see #881).
To avoid the 404 in the hosted examples, the css is copied to the same relative path when hosted as during development.
The makeChildAppender function is used for adding a node of a
type with maxOccurs=1. For adding nodes of a type with
maxOccurs>1, the new makeChildrenAppender function was added.
With this new function, it turned out that more convenience for
creating node factories is required. The makeChildNodeFactory
function was renamed to makeSimpleNodeFactory, and it now can
create node factories where not only the namespace, but also the
node name can be fixed.
This adds several helper functions for serializing to XML:
* ol.xml.serialize: Counterpart to ol.xml.parse. By splitting
the serialization process up into a node factory and a node
writer, note writers can easily be used for different
namespaces.
* ol.xml.pushSerializeAndPop: Counterpart to
ol.xml.pushParseAndPop.
* ol.xml.makeStructureNS: Works like ol.xml.createParsersNS,
but works for arbitrary structures.
* ol.xml.makeChildAppender: If the top item of the stack has
the new ol.xml.NodeStackItem type, this helper function
can be used to create a serializer that appends the current
node to its designated parent.
* ol.xml.makeChildNodeFactory: Creates a node factory which
produces child nodes from an array of node names which are
passed to ol.xml.serialize.
* ol.xml.makeSequence: A convenience function for creating
xsd:sequence structures. Takes an object literal and an
ordered list of the keys, and returns an array that can be
passed as values to ol.xml.serialize.
* ol.xml.makeSimpleTypeWriter: Using e.g. the new write*TextNode
functions from ol.format.XSD, this function creates a node
writer that writes simple type nodes for values like strings
or numbers.
The following commits will be using this new framework for
implementing ol.format.GPX.writeFeatures, and prose
documentation with instructions based on what was said above
will be added.
