This change introduces a new 'replace' mode for tile transitions: when the
resolution does not change, which happens when mergeNewParams is called,
the tile will be marked with the .olTileReplace class. If this class sets
the tile's imgDiv display to 'none', the backbuffer for the tile will
immediately be removed when the tile is loaded.
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.
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.
OpenLayers.INCHES_PER_UNIT.m should equal
OpenLayers.INCHES_PER_UNIT.Meters, just like OpenLayers.INCHES_PER_UNIT.km
should equal OpenLayers.Inches_PER_UNIT.Kilometers. This confusion probably
comes from mixing International inches with US Survey inches when compiling
the unit conversion list (1 meter is 39.37007874 International inches, but
39.37 US Survey inches. It may not be obvious, but 'inches'/'Inch' in
OpenLayers means US Survey inch, and 'IInch' means International inch).
This change also fixes offsets caused by incorrect resolution calculations in
OpenLayers.Format.WMTSCapabilities.
The new minFrameRate option is used to make sure that an animation does not
run longer than the time calculated from that frame rate. Time is made up
by skipping frames, i.e. skipping execution of the eachStep callback.
