[raj1258]

• avoid transformation of coordinates in case coordinate system is WGS84(longlat) projectio string is present in '.prj' file
• it ll solve the floating decimals issue in coordinates

there are lat long coordinate systems that are not wgs84, a better thing might be a pull to proj4 that makes sure that an attempt to convert from wgs84 to wgs84 is just a pass through.

This is really not a bug because those "changed coordinates" should be mathematically equivalent in floating points
