update with current cesium (#1)

* Added tests for DiscardEmptyTileImagePolicy, updated CHANGES.md

* Made comment on image blob loading error handling clearer.

* fixed linter error - 'missing use strict'

* Fix typo.

* Remove fit.

* Update CHANGES.

* update CHANGES

* eslint configuration updates and fixes

* Update Node ecmaVersion to '2019'.
* Enable [no-tabs](https://eslint.org/docs/rules/no-tabs).
* Enabled [no-restricted-globals](https://eslint.org/docs/rules/no-restricted-globals) for jasmine `fit` and `fdescribe`.
* Remove existing tabs from code-base.
* Update eslint-config-cesium CHANGES and version

Closes CesiumGS#7785

* Fix PostProcessStageTextureCache.clear, which previously didn't clear anything.

* Multisampling in sdf shader to try to get rid of artifacts

* Use DiscardEmptyTileImagePolicy for all Bing styles.

This removes the need to inspect pixel values to detect the placeholder "missing tile" image.

Also change `DiscardEmptyTileImagePolicy.EMPTY_IMAGE` to be a real (blank) image.
This way we always satisfy the documented API of `requestImage`.

Fixes CesiumGS#1353.

* Add syntax to to delete data from properties via CZML.

Specifying delete: true for any property will delete data for that property, depending on the type of property, for the specified interval (or if no interval is specified, then for all time).

This deletes samples for sampled properties, or removes intervals for interval properties.

* Much improved multisampling of the SDF text

* Fixes CesiumGS#7827

* Fix double render.

* First crack at importing AGI_articulations from glTF models.

* Some tweaking, and add option to get list of articulations.

* Add 3D Models Articulations demo.

* Fixed writeTextToCanvas to properly position the text with padding above
and below the glyph.  Previously it was doubling the padding so it was
always rendering the glyph at the very top of the canvas

* Added bitmap-sdf library

* Don't send ion access token to non-ion servers

Some ion-hosted assets can still point to additional external servers as,
part of their dataset. We were still appending the ion access_token in
the Accept header to these servers, which is at best pointless but at worst
would cause some CORS requests to fail because the Accept header was not
allowed.

* Update CHANGES

* Added SDFSettings class to hold info about how SDF fonts are generated.
Replaced tinySDF based code with a modified version of the original
cesium text rendering to preserve positioning logic.
Applying offsets in LabelCollection and Label bounding box compuation to
account for padding in the glyphs to position things correctly.
Enabled more unit tests in LabelCollectionSpec

* Fix include

* Simplified sdf shaders to push edge computation to the CPU.
Deleted tiny-sdf

* saving vertical origin in texture cache id

* Updated unit tests

* Documented totalScale in Label and using it in few places in LabelCollection

* Updated Labels SDF gallery image

* Add tests that delete data from custom properties since the code path is a bit different.

* Hook up existing CheckerboardMaterialProperty to CZML.

CheckerboardMaterialProperty was added to the entity API in CesiumGS#2385 but
was forgotten for CZML.

* Reduce Bing Maps transactions and ion Bing sessions

This is a simple PR to try and minimize the number of Bing transactions
and ion Bing sessions over the course of a page. While we can't cache
Bing metadata or ion endpoints across sessions, this type of basic caching
is allowed and should dramatically reduce use for certain use cases.

1. BingMapsImageryProvider now keeps a local cache of metadata for a given
url/style. This means destroying and recreating instances multiple times
still only uses a single transaction.

2. IonImageryProvider now caches endpoint requests. This means that
creating multiple IonImageryProviders for the same Bing asset will only
use a single Bing session.

While use cases like Sandcastle, which uses an iframe, won't benefit at
all from this change, applications that switch base layers often or
destroy/recreate the viewer as part of a SPA will see dramatic improvement.

* Initial commit of KML exporter

* Update changes.

* Removed unnecessary comments in Label.js

* Fixed background padding size computation in LabelCollection so that the
specified size in pixels is scaled properly when finally rendered

* MapboxStyleImageryProvider

- Rename from MapboxStyleProvider
- Modify CHANGES.md
- Add reference to ImageryProvider class

* Added support for Rectangle and Polygon graphics.

* chore(package): update merge-stream to version 2.0.0

* Add test for articulations

* Remove getter for articulationStageKeys, it's not useful by itself.

* Make ImageBitmap test only run when ImageBitmap is supported

* Update changes [ci skip]

* update changes.md

* Added tests for dynamic points. Added code for path graphics and labels. Fixed polygons. Fixed handling of default intervals

* Added a bunch of tests

* Polygon and Polyline tests work.

* Models

* Fixed typo in LineString

* Tweak CSS styling of standalone Sandcastle loader

* Gamma correct fix for polylines

* CHANGES.md

* Ground Overlay support

* Add articulation tests to CzmlDataSourceSpec.js

* Reorder code in entity layer to have consistent order of properties.

Previously the list of properties for each type of Graphics in the entity layer was different everywhere.  This made it quite difficult to compare the set of properties in the code vs the set of properties in CZML. I went through and reordered all these locations to have properties in the same order in each.

* The documentation for the constructor for each graphics type
* The content of the constructor (initializing `_property` and `_propertySubscription` to `undefined`)
* The public get/set properties
* The contents of the `clone` function for each graphics type
* The contents of the `merge` function for each graphics type
* The code assigning the values of properties in `CzmlDataSource`.

Also add some missing functionality to `CzmlDataSource`:

`box.heightReference`
`cylinder.heightReference`
`ellipsoid.heightReference`

`corridor.classificationType`
`ellipse.classificationType`
`polygon.classificationType`
`polyline.classificationType`
`rectangle.classificationType`

* Update validation document.

* Update validation document.

* Updated Corporate CLA

* Update deprecated Travis command

* support for ArcGISTiledElevationTerrainProvider

* Added ArcGISTiledElevationTerrainProvider under Additions/1.59.

* eslint

* Removed debugging info from Labels SDF sandcastle demo

* Changed SDF vertex attributed to be a vec2 instead of a vec4 since the z and w components were 0

* Storing canvas width and height in local variables in LabelCollection
Storing imageIndex as a local variable to avoid redundant compuations

* Remove blank line in BillboardCollectionFS.glsl

* Added bitmap-sdf to third party section of LICENSE.md

* Renamed SDF to SDF_INDEX to match other index location naming
convention.

* Updated Sandcastle filename with a case difference

* Replace old CLA txt with new CLA PDF

* Added link to Labels SDF sandcastle example to CHANGES.md
Added Label.totalScale property to CHANGES.md

* update export KML doc and Sandcastle

* Changed getFontInfo function to be parseFont and moved it to Label.
Rather than keeping a fontInfoCache in LabelCollection the font
properties are stored on the Label itself and the parseFont function is
called when the font string changes.

* link update

* fix

* Make PolygonGraphics.hierarchy always produce a PolygonHierarchy.

For backwards compatibility we preserve the existing behavior of allowing an array of positions to be set.
This makes the behavior more closely match the documentation. The ability to set an array of positions
was undocumented, though some Sandcastle examples do this.

This removes the need for conversion in PolygonGeometryUpdater at the point where the data is used.

* Make code more consistent between processArrayPacketData and processPositionsPacketData

* Clean up test code.

Use CzmlDataSource.load in most tests. Compare against the values from the packet data rather than copy/pasting the expected values.

* Add support for polygons with holes to CzmlDataSource.

* Add additional tests

* Add more tests. Fix incorrect behavior with reference arrays specified using intervals.

* Add more tests.

* Update validation document.

* Add more tests.

* In PolygonHierarchy, holes needs to be an array of PolygonHierarchy.

* Add holes to CZML polygon Sandcastle examples.

* fix typo

* update CHANGES

* fix typo

* update CHANGES

* Regenerate validation document and assertions.

* fix typo
