Cleaned up gesture recognizers, flipping the origins of anchor points only and always before calling mbgl methods. This exposed the fact that the cursor locking feature during drag-zoom/rotate/tilt was broken, so I fixed it to match MapKit behavior exactly and also account for modifier changes in mid-gesture.
Mapbox OS X SDK
A library based on Mapbox GL Native for embedding interactive vector maps into Cocoa applications on OS X 10.10.0 and above using Objective-C, Swift, or Interface Builder.
This SDK is analogous to the Mapbox iOS SDK, and much of the iOS SDK documentation applies here. Mapbox does not officially support the OS X to the same extent as the iOS SDK; however, bug reports and pull requests are certainly welcome.
