Test failures in IE 11

[mramato]

After #2859, there are still 5 test failures in IE 11 that we should investigate

Renderer/CubeMap draws with a cube map with premultiplied alpha
Renderer/Texture renders with premultiplied alpha
Scene/Pick drill picks multiple objects
Scene/Pick does not drill pick when show is false
Scene/Primitive can disable picking when asynchronous

With Cesium 1.17, there's two need test failures in IE 11:

• Scene/WebMapServiceImageryProvider pickFeatures works with THREDDS XML format
• Scene/WebMapServiceImageryProvider pickFeatures works with msGMLOutput format

@RacingTadpole can you take a look at this?

[RacingTadpole]

Sure. For my future ref, I've just tried the tests in a Win8 IE10 environment, and get the error:
Failed: promise rejected: TypeError: Unable to get property 'value' of undefined or null reference. The offending code is in https://github.com/AnalyticalGraphicsInc/cesium/blob/master/Specs/Scene/WebMapServiceImageryProviderSpec.js#L559 and https://github.com/AnalyticalGraphicsInc/cesium/blob/master/Source/Scene/GetFeatureInfoFormat.js#L230 .
I'll take a look soon.

[RacingTadpole]

Oops, sorry. Yes, I only fixed the two new failures, THREDDS XML and msGMLOutput.

New failures in 1.18:
Scene/DeviceOrientationCameraController rotates for alpha
Scene/DeviceOrientationCameraController rotates for beta
Scene/DeviceOrientationCameraController rotates for gamma

The errors I see in 1.19:

These tests work when run individually:
Scene/Pick drill picks multiple objects
Scene/Pick does not drill pick when show is false

These tests are really close to the expected results, seems like precision / rounding issues.
Renderer/CubeMap draws with a cube map with premultiplied alpha
Renderer/Texture renders with premultiplied alpha

Renderer/CubeMap fails to generate mipmaps (width) is failing because IE does not support non-power-of-two cube maps (source)

New failure in 1.24
Scene/GroundPrimitive creating a synchronous primitive throws if initializeTerrainHeights wasn't called

Failures in 1.25

From before:

Renderer/CubeMap draws with a cube map with premultiplied alpha
Renderer/Texture renders with premultiplied alpha
Scene/GroundPrimitive creating a synchronous primitive throws if initializeTerrainHeights wasn't called

New ones:
DataSources/KmlDataSource when a LineString is clamped to ground and tesselated, entity has a corridor geometry and ColorProperty (Object.assign not supported in IE11)

Widgets/Viewer/Viewer does not crash when tracking an object with a position property whose value is undefined.

These two only pass when run individually:
Scene/GeometryRendering WallGeometry pick
Scene/GeometryRendering Extruded PolygonGeometry pick

These all seem to be related:
DataSources/RectangleGeometryUpdater color material sets onTerrain to true
DataSources/RectangleGeometryUpdater fill is true sets onTerrain to true
DataSources/RectangleGeometryUpdater dynamic updater on terrain
DataSources/RectangleGeometryUpdater Checks that an entity without height and extrudedHeight and with a color material is on terrain
DataSources/PolygonGeometryUpdater color material sets onTerrain to true
DataSources/PolygonGeometryUpdater fill is true sets onTerrain to true
DataSources/PolygonGeometryUpdater dynamic updater on terrain
DataSources/PolygonGeometryUpdater Checks that a polygon without per position heights is on terrain
DataSources/PolygonGeometryUpdater Checks that an entity without height and extrudedHeight and with a color material is on terrain
DataSources/GeometryVisualizer StaticGroundGeometryColorBatch updates color attribute after rebuilding primitive
DataSources/EllipseGeometryUpdater color material sets onTerrain to true
DataSources/EllipseGeometryUpdater fill is true sets onTerrain to true
DataSources/EllipseGeometryUpdater dynamic updater on terrain
DataSources/EllipseGeometryUpdater Checks that an entity without height and extrudedHeight and with a color material is on terrain
DataSources/CorridorGeometryUpdater color material sets onTerrain to true
DataSources/CorridorGeometryUpdater fill is true sets onTerrain to true
DataSources/CorridorGeometryUpdater dynamic updater on terrain
DataSources/CorridorGeometryUpdater Checks that an entity without height and extrudedHeight and with a color material is on terrain

Now the only failures that happen consistently are:

Renderer/CubeMap draws with a cube map with premultiplied alpha
Renderer/Texture renders with premultiplied alpha

Other test fails when run with all, but pass when run individually.

[bagnell]

Test failures in 1.26

Scene/LabelCollection can render after adding a label
Scene/GroundPrimitive renders with distance display condition per instance attribute

These tests pass when run individually:
Scene/GeometryRendering PolygonGeometry pick
Scene/GeometryRendering Extruded PolygonGeometry pick

New test failures in 1.28

DataSources/CorridorGeometryUpdater A time-varying color causes ground geometry to be dynamic
DataSources/EllipseGeometryUpdater A time-varying color causes ground geometry to be dynamic
DataSources/PolygonGeometryUpdater A time-varying color causes ground geometry to be dynamic
DataSources/RectangleGeometryUpdater A time-varying color causes ground geometry to be dynamic
Scene/LabelCollection renders label with distanceDisplayCondition

@bagnell I'm assuming the first 4 are because of lack of ground primitives in IE and the other one caused by the same issue as Scene/LabelCollection can render after adding a label?
