uint32_t GetSmallMapOwnerPixels ( TileIndex  tile,
TileType  t,
IncludeHeightmap  include_heightmap

tEffective tile type of the tile (see SmallMapWindow::GetTileColours).
include_heightmapWhether to return the heightmap/contour colour of this tile (instead of the default land tile colour)
Returns
The colour of tile in the small map in mode "Owner"

const Station st 
)
