Symbolizer that fills everything?

[zdila]

For compositing operations (comp-op) I would like to have a symbolizer that fills the whole map. So far I am working it around using PolygonSymbolizer with inline geojson polygon and +init=epsg:4326 srs

{
  "type": "Polygon",
  "coordinates": [
    [[-180, -90], [-180, 90], [180, 90], [180, -90], [-180, -90]]
  ]
}

Unfortunately it doesn't play well with different srs in Map (for exmaple +init=epsg:3035). My app uses parameterized srs so I can't hardcode this polygon.

Is there a way to solve it nicely?
