This makes it possible to read polygons or multipoints too. Since the
encoded format is just a list of points the reader needs to be told what
Feature to create from the encoded list.
The example code is edited to reflect that API extension.
This allows users to control whether 3d acceleration should be used or not:
Just like with plain web pages, having a stylesheet that sets a transform
on the map's layerContainerDiv will make OpenLayers use translate3d and
scale3d. When no such transform is set in the stylesheet, style.left and
style.top will be used, except for e.g. pinch zoom, where scaling is
needed.
In current Webkit browsers, having translate3d on svg child elements
causes the positioning from the layer not to be inherited by the vector
layer content.
The loadend event of an image is fired before the image is rendered. For
standard 256x256 tiles, this does not matter. But for singleTile layers on
large screens, rendering time needs to be considered. So we add a delay
that depends on the tile size. TODO: make the denominator configurable.
The navigation control gets better defaults, and the MouseWheel handler
gets a new maxDelta option, which can be used to avoid huge zoom level
jumps on heavy wheel/pad movements.
Having the TileManager remove an image from the DOM, then setting the
cached image, and then having to position it felt a bit awkward. With the
new beforeload event, the setImage method and putting renderTile before
positionTile, providing the cached image feels way more natural.
We now reuse tile images by maintaining a cache of image elements with a
simplified LRU expiry policy (by order, not by timestamp). The tile queue
is bypassed for images that are available in the cache, so they can be
rendered immediately. And the tile queue itself loads more than just one
image at a time now (2 per layer url).
Previously, minFrameRate could not be set as option with the start method.
The tests failed to catch this flaw. Now both the start method and the
tests are fixed.
