MapView

Zoom and pan animation APIs now accept an additional interpolator parameter.

Reduce object allocations

• Greatly improve performance when having remote HTTP, leveraging back pressure (the view-model waits the collector when the latter is overwhelmed).
• Added tutorial to make a deep-zoom map.

• Now use a specific Dispatcher which sets the thread priority so they have less chance of impacting UI.
• Added remote HTTP demo

Minor issue on visible tile calculation lead to some tiles being unnecessarily requested - fixed.

Previous version was using THREAD_PRIORITY_LOWEST, which can lead to UI hang on some emulators, while THREAD_PRIORITY_BACKGROUND has similar positive impact on overall responsiveness on low-end devices while not having this side effect.

The configuration of the MapView can now be done at any time after the MapView creation.

This first version is production ready and has been thoroughly tested.
