- Added Layer/FixedZoomLevels.js, which is a new pseudo-layer that all layers
which have fixed zoom levels will need to extend. It provides alternative
methods to initResolutions(), getResolution(), and getExtent() which depend
on the fixed zoomlevel layer implementing getLonLatFromViewPortPx(),
getViewPortPxFromLonLat() and getZoomForExtent(). For documentation of how
this works, see the comments in the class header.
