Create setSortableLayers function into searchResultsTable and inserted function into attachEvents
Add layerId as id value for each rowContainer (e.g. 'id = "arizona_censusBlocks_2015" ' ). Allows us to tie zIndex value to div position in previewedLayers when layer(s) are dragged around.
Change cursor on previewedLayers hover to let user know that layer position can be changed with drag and drop
Previewed layers sortable
…. Previously, the bounding box would be passed regardless of raster pixel alignment. This would cause the raster to be transformed to coincide with the bounding box. Changes made allow for the bounding box to be snapped to the nearest raster pixel edge so that a transformation will not take place. This was causing a particular issue with multi-band raster where 0 values in a pixels R,G,B values (i.e. 145,0,79) would be set to the whole pixel to "no-data" in transformation, resulting in pixel holes throughout the image.

There was a problem hiding this comment.
No longer need generateSize. The getCoverageRequest string is composed near the end of the file.

…. Previously, the bounding box would be passed regardless of raster pixel alignment. When geoserver would recieve the WcsGetCoverage request where either the bounding box mins and maxs divided pixels OR if resx&resy were specified instead of width&height, it would cause a JAI warp operation which was transforming the produced raster to correspond to the bounding box. Changes made allow for the bounding box to be snapped to the nearest raster pixel edge instead so that a transformation will not take place. As well as shifting the raster, this was causing a particular issue with multi-band raster where 0 values in a pixels R,G,B values (i.e. 145,0,79) would be set to the whole pixel to "no-data" in transformation, resulting in pixel holes throughout the image.
