This updates ESLint and our shared eslint-config-openlayers to use Prettier. Most formatting changes were automatically applied with this:
npm run lint -- --fix
A few manual changes were required:
* In `examples/offscreen-canvas.js`, the `//eslint-disable-line` comment needed to be moved to the appropriate line to disable the error about the `'worker-loader!./offscreen-canvas.worker.js'` import.
* In `examples/webpack/exapmle-builder.js`, spaces could not be added after a couple `function`s for some reason. While editing this, I reworked `ExampleBuilder` to be a class.
* In `src/ol/format/WMSGetFeatureInfo.js`, the `// @ts-ignore` comment needed to be moved down one line so it applied to the `parsersNS` argument.
* Rename ol.vec.Mat4.fromMatrix to ol.vec.Mat4.fromTransform
* Make result from ol.vec.Mat4.fromTransform immutable by adding result
matrix as argument.
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.
