Both Android and iOS now use pause/resume. The map thread is
always running, and be able to receive messages. When paused,
it will just refuse to render.
This brings the easing transition code a bit closer to how easings work
in gl-js. Instead of having an array of individual transitions for scale,
rotate, and pan, there is a single transition function that does all the
required calculations. This permits us to:
* Eliminate the "timeout" transition. (Fixes#126)
* Replace start/stopPanning() et al with setGestureInProgress(). Apps or
SDKs are expected to make paired calls to setGestureInProgress(). This
state will be ORed with the active easing state to determine when to
use texture interpolation. (Fixes#79)
* Run style recalculations only when an ease transition that affects the
zoom is in progress. (Fixes#1155)
fixes#838
instead of rendering ad libitum on the map thread, we are now driving rendering from the UI thread on iOS via the map.renderSync() function. There are still white bars during the rotation, but the general content of the view is kept visible.
- upgrades GLFW to 3.1
- removes swapped/needsSwap in favor of a more explicit scheme
- View#invalidate() now replaces View#swap() and is called whenever the View needs to trigger a rerender. GLFW and Android to this right away, while iOS goes back to the main thread and does the Map redrawing as part of the GLKView update
- sets all iOS deployment targets to 7.0
- disables SQLite3 version check, since the library version changed on iOS 8.2
