* [core] Parse TileJSON bounds property
* [core] Add TileRange and LatLngBounds::contains(CanonicalTileID)
Move LatLngBounds::contains impl to cpp file
* [core] Skip tile creation outside of tileset bounds
* [core] Fix TileRange for wrapped bounds and use for CustomTileLoader instead of LatLngBounds comparisons for tiles.
Core test uses stubbed "glyph.pbf" without Chinese glyphs
Darwin test relies on locally available "PingFang" font.
Android test relies on locally available "Droid" font. 'expected.png' is NOT correct b/c I haven't figured out how to run unit tests on Android yet.
- Platform-specific LocalGlyphRasterizer is responsible for deciding which glyphs to rasterize locally and for implementing the rasterization.
- Default platform implementation doesn't locally generate any glyphs -> no behavior change
- Unit test uses StubLocalGlyphRasterizer, which returns a single fixed bitmap for all CJK glyphs
- Rename glyph_loader.test to glyph_manager.test
Enables -fvisibility=hidden for iOS and Linux, and adds a workaround for GCC 6.3-7.1
Adds a GCC 6 build
Enables diagnostics for C files
Fixes a shadow warning in parsedate.c
- Switches from tile to viewport coordinates
- Represents line labels with circle geometries
- Projects line labels at collision detection time to improve accuracy
- Adapts tile-based symbol queries to viewport coordinates
This class is responsible for tracking which symbols are "the same" between tiles at different zoom levels, so that symbol opacities (fade animations) can be copied smoothly between tiles.
Previously, we used the existence of a `prior*` field in the Resource object as an indication for whether we should consult the cache or not. However, this is prone to error, since a failed cache lookup won't set any prior fields. Therefore, we manually set `priorExpires` to 0. This in turn triggered another bug where generated wrong expiration timestamps when the server response we got was expired (or expired between sending and receiving).
This commit changes the flags so that we can now explicitly request CacheOnly/NetworkOnly (or All) loading methods, rather than the implicit Optional/Required naming scheme.
