This fixes following issues:
* Fix some false passing combinations/fill-extrusion-translucent--XXXX tests
* Fix and enable other, failing but ignored, combinations/fill-extrusion-translucent--XXXX tests
* Fix rendering of layers that are on top of fill-extrusion layers
state.getProjMatrix(nearClippedProjMatrix, 100) caused that tests with size 64x64 were not
rendering fill extrusions: far plane calculated as 96.9 and near plane set to 100 was the cause.
near plane is changed from hardcoded 100 to depend on state.getCameraToCenterDistance() - producing
similar value but one that follows max zoom.
This caused that e.g. combinations/fill-extrusion-translucent--fill-opaque was falsely passing as
only fill-opaque layer got rendered.
combinations/fill-extrusion-translucent--XXXX tests expose regression https://github.com/mapbox/mapbox-gl-native/issues/14844#issuecomment-503600034 in #14844, #14779.
Fix (opaquePassCutoff, is3D) is ported from https://github.com/mapbox/mapbox-gl-js/pull/7821Fixes: #14844, #14779, #15039
Now `RenderLayer::upload()` accepts only `uploadPass`, similar to other uploadable objects.
Few simplifications were made in the `LineLayer` prepare stage.
RenderTile and Tile will be split when ochestration movces to a separate thread.
This PR improves encapsulation of Tiles management: now performed within TilePyramid.
`RenderSymbolLayer` does not have to update dynamic vertices of its buckets, this logic is moved to placement (which is already updates opacity vertices).
* fixes clustering of labels when text variable placement enabled - as assignes `usesVariablePlacement` per bucket
* simplifies the code in `RenderSymbolLayer` (the `RenderSymbolLayer::upload()` is now omitted).
* symbol buckets are not modified after orchestration finishes
- Do not carry it over everywhere as parameter, it is a shared
instance anyway and the lifecycle is pretty much the app lifecycle
from the moment we instantiate a map.
- Rename to BackgroundScheduler because it is a Scheduler that will
do tasks in the background, we don't make assumptions if it is a
thread pool or a single thread.
- Most importantly, remove the dependency from `core` on `platform`.
- Track images provided by client thruough onStyleImageMissing API
- Handle reduceMemoryUsage in ImageManager, via Renderer API
- Release client provided images when no tiles are using them
This simplifies the code and make it slightly more performant.
Also, this change enables initialization the `RenderTile.used`
field from inside the source (currently done in render layers).
