When the map is at the highest zoom level, the old and the current
resolution will be the same. This would cause a division by zero, which
the JavaScript engine does not recognize as such. So we have to protect
zoomOriginPx from becoming {x: Infinity, y: Infinity}.
Selecting the same feature again should not do anything, which was ensured
in the old implementation by a check in the SelectFeature control. This
means that the previous commit causes a change in behavior in standalone
mode, which I would consider a bugfix. I documented this change in the
release notes.
For events other than move, the tile queue may not be populated yet when
updateTimeout is called. So instead of checking for the queue's length,
we register the timer unconditionally in these cases.
This commit is a follow-up on issue #294 (commit a6119f6) and #861 (commit c7a4045). The feature handler should not stop the bubbling up of browser events. In this particular case, when the feature handler is activate, Sencha Touch will trigger longpress events when panning the map because the feature handler stops touchmove.
Because OpenLayers.Util.getParameters turns comma delimited values into
arrays, comparing e.g. bbox values in urls will return false. By
introducing a splitArgs option, we can use getParameters in a way that
leaves such values as strings and makes them comparable in
OpenLayers.Util.isEquivalentUrl.
In OpenLayers 2.12, only one tile was loaded per animation frame. This
change brings back something similar as part of the tile manager. But we
do not use requestAnimationFrame anymore, because @elemoine pointed out
that browsers may give requestAnimationFrame invoked functions a higher
priority than setTimeout invoked functions.
The reason for this change is

The W3C standard says that setAttribute/getAttribute on any DOM element is
a simple setter/getter thing. IE8 tries to be smarter and returns the full
URL when calling getAttribute('src') on an image instead of the one that
was set with setAttribute('src').
This change makes sure that urls are compared properly, also in IE8.
