If a load fails then we won't have any features, but we also won't
try and load them again for any part of that area because the bounds
tell us we have already loaded them. So clear the bounds in order
that reloads will be triggered.
Calculating pixel positions from origin and grid index causes alignment
issues in the grid. By going back to incremental positioning, we get a
result without blank spaces between tiles again.
This also fixes an issue that has gone unnoticed for a while: the grid did
not cover the bottom of the map viewport, but instead covered an invisible
area above the top of the map viewport.
Now we also do not use deltas for shiftRow and shiftColumn. Some
refactoring was done so we do not need different calculateGridLayout
methods for layers with top-left and bottom-left tile origin.
TODO: With this commit, ArcGisCache and KaMap layers are broken.
Move the changelayer event firing logic for in / out of resolution range
from the Map class to the Layer class. Tests have been also been created
to specifically test that the display method works correctly and fires
events only when needed.
The [URI standard](http://tools.ietf.org/html/rfc3986#section-4.2) allows for URI without a scheme. Where http is used to load the app, using a schemeless URL for the Bing metadata loads a script using http - and the same goes for https.
The WMSDescribeLayer format currently differs from other formats that
inhreit from VersionedOGC by having an array instead of an object as return
type. This especially bad since the VersionedOGC superclass sets a version
property on the array. With this change, the WMSDescribeLayer format will
also be compatible with GeoServer's new JSON response type for
DescribeLayer - see
http://sourceforge.net/mailarchive/message.php?msg_id=29912776.
Another change included here is the removal of the WMSDescribeLayer
format's getVersion hack, which was replaced by a generic fallback to less
generic parsers, e.g. from a v1_1_1 parser to a v1_1 parser if v1_1_1 is
not implemented.
With this change, createLayer generates url arrays for both KVP and REST
encoding if multiple resource urls are provided. To make this work, the
WMTSCapabilities format got a new resourceUrls property, because
previously only the first resourceUrl for a format was stored.
