* Min and max number of points configurable for lines and polygons
* Polygons from custom geometryFunction now have a sketch line
* The example shows how to use a custom geometryFunction
This allows applications to control the geometry that is created from the
drawing sketch. Will e.g. be useful to create a regular polygon instead of
a circle when in Circle mode.
The addition of full extent tile ranges also allows us to simplify wrapX
handling for tile layers. By limiting wrapX to true and false as possible
values, we can remove a lot of guessing logic.
Please write blog posts, create tutorials, or develop workshops that show off cool ways to develop applications that use OL3. The examples should be kept very simple. This download functionality is neat, but it's really a gratuitous use of non-map related functionality. While it does demonstrate the use of `format.writeFeatures()`, this is buried in too much additional code that is not accessible (buried in resources/common.js) and not really related to mapping things. If we want to have examples that demonstrate how formats can be used to serialize features, a simple textarea would suffice as the target.
This addition is related to the definition of olx.FrameState in olx.js. Without this alias and corresponding goog.provide in src/ol/vec/mat4.js we get this error when compiling an OpenLayers application:
ERR! compile node_modules/openlayers/externs/olx.js:6853: ERROR - Bad type annotation. Unknown type goog.vec.Mat4.Number
ERR! compile * coordinateToPixelMatrix: goog.vec.Mat4.Number,
Currently, the Closure Library does not have a goog.provide for goog.vec.Mat4.Number. If it did have this goog.provide then we wouldn't have the error.
This commit works around the issue by creating our own type alias (ol.vec.Mat4.Number) and adding a goog.provide for that type alias.
By having the abstract methods in the base class, subclasses can simply
override the methods they actually provide.
Additionally, this change fixes a regression in webgl canvas immediate.
