Since placements will be committed even if they do not need the full
fade duration to fade features in, we need the new `fadeStartTime` to
keep track of how long we still need to fade. This is important because
if we fade too long we will trigger another placement and never stop
rendering.
* Fix crash due to mixing legacy filters and expressions
In some cases, (invalid) nested filters that used a mix of legacy filter
syntax and expression syntax caused a crash due to a failure to
propagate parsing errors from deeper within the filter expression.
These errors went undetected in part because these conversion functions
returned unique_ptr<Expression> values (or vectors thereof), using
{nullptr} to represent a parsing error, but the core expression classes
expect unique_ptr<Expression> that are never null.
This changes over to using expression::ParseResult (aka
optional<unique_ptr<Expression>>), to represent conversion failure
the same way we do in the rest of the expression system.
* Fix clang 3.8 / gcc 4.9 issue
GLIBC 2.27 added new versioned symbols of powf and logf, while the double versions of pow and log remained stable.
Prefer the double version to avoid introducing a dependency on a newer version of GLIBC than strictly necessary.

Makes `["match", ["get", k], label, match, otherwise]` equivalent to `["case", ["==", ["get", k], label], match, otherwise]`. This changes the behavior of match expressions where the runtime type of the input does not match the type of the labels: previously such expressions produced a runtime type error and then fell back to the property default value; now they produce the fallback value from the match expression.
Native version of mapbox/mapbox-gl-js#6548.
Port of mapbox/mapbox-gl-js#6550.
Prevents symbols that share the same layout properties from colliding against each other.
Bump GL JS pin to get regression test.
Rename "bucketName" -> "bucketLeaderID" to make it clearer what it represents.
Previously we relied on tile buffers for querying features who's
rendered representations cross tile boundaries. Now we query multiple
tiles making it unnecessary to index features that are completely
outside a tile's boundaries.
- assert symbol layer tiles must be geometry tiles, instead of dynamically checking
- re-use retainedBucketQuery iterator instead of calling find twice.
- Pulls over an update to line.vertex.glsl (looks like a no-op?)
- Add test ignores for collator, is-supported-script, line-gradient
- Exclude collator, is-supported-script, line-gradient from code generation.
- Symbol querying is now global instead of per-tile
- Symbols that bleed over tile boundaries no longer missed in queries
- Symbol results now sorted based on rendering order (ie overlapping symbols change their sort order when a bearing change causes their render order to change)
- Placement::retainedQueryData now responsible for maintaining symbol querying data for buckets that may no longer be in the TilePyramid.
Fixes issue #11729. Close relative of issue #10956.
It is possible for us to receive Glyphs from the server that are valid, but have an invalid bitmap. In that case, the glyphs will be present in the `GlyphMap` used for shaping, but not present in the `GlyphPositions` used in `getGlyphQuads`. `SymbolInstance::hasText` looked at the shaping instead of the actual quads.
`symbol_projection.cpp` should never try to project a label without any quads, but we'll also try to make it so that it doesn't crash if it does.
- On some gl implementations the uniform locations are shifted after linking the program a second time, resulting in errors when using any uniform. On some implementations they are actually doubled. Re-binding the uniforms after selectively binding the vertex attributes prevents this.

Prevents querying a FeatureIndex built against a separate set of data, which can lead to invalid index exceptions.
The GeometryTileWorker 'data' member can still change independently of the data in the feature index, at the time 'setData' is called. The GeometryTileWorker maintains ownership of its local data (which may be used to re-parse) and clones the data for use by the FeatureIndex in the foreground.
