Replaced Markdown syntax with HTML syntax for hyperlinks in documentation comments. HTML links work both inside Xcode (whether Objective-C or Swift) and on the Web (via jazzy).
Fixes#3961.
Added an API for deleting unused annotation images’ images. When you nil out the image of an MGLAnnotationImage, MGLMapView deletes the sprite from the style and recreates any annotation associated with the MGLAnnotationImage instance; the MGLAnnotationImage’s falls back to SDK’s default annotation image.
In iosapp, deselecting an annotation resets its image to the default; deselecting it again restores the image.
ref #3185
Use UIView animation to explicitly animate the user dot between user location updates. There is a tricky special case, which is that the callout must point to the annotation view’s implicit frame but must quickly rendezvous with the explicit frame.
Fixes#1041.
Include offline headers in the umbrella header used by the static framework. These includes are already present in the umbrella header used by the dynamic framework. jazzy relies on the static umbrella header to include all the headers, so the offline headers were also missing from documentation.
