OpenLayers. Layer

{Integer} Determines the width (in pixels) of the gutter around image tiles to ignore.  By setting this property to a non-zero value, images will be requested that are wider and taller than the tile size by a value of 2 x gutter.  This allows artifacts of rendering at tile edges to be ignored.  Set a gutter value that is equal to half the size of the widest symbol that needs to be displayed.  Defaults to zero.  Non-tiled layers always have zero gutter.

{String} Set in the layer options to override the default projection string this layer - also set maxExtent, maxResolution, and units if appropriate.

{String} The layer map units.  Defaults to ‘degrees’.  Possible values are ‘degrees’ (or ‘dd’), ‘m’, ‘ft’, ‘km’, ‘mi’, ‘inches’.
