* [core] geometry.hpp 0.8.0
* geojsonvt @ 6.0.0
* Update platform deps, build scripts
* Perf optimizations/cleanup
* Rebase in geometry@080
* D.R.Y. etc
* Ensure fill annotation geometries have closed rings.
* Optimizations
* Update to geojsonvt @ 6.1.0 for clean handoff between geojson parsing and geojsonvt
* Apply close multi/poly geoms for line annotations as well
* Main gyp files are now standardized as platform/<platform>/platform.gyp.
* Each platform gyp file defines appropriate loop_lib and headless_lib variables.
* Each platform gyp file includes mbgl.gypi, which defines base targets which may be useful to all platforms.
* CI targets are consistent across platforms: `make $(PLATFORM) && make test-$(PLATFORM)`.
* Renamed the "linux" test app to "glfw". It's now built in OS X CI.
* Android build flakiness is fixed.
* iOS CI builds the bench and iosapp targets.
* Mesa version is now in one place.
