2003-03-25  Frank Warmerdam  <[e-mail]>

2003-03-17  Frank Warmerdam  <[e-mail]>

	* src/pj_datums.c: changed NAD27 definition to make everything
	optional, and to include alaska, and ntv2_0.gsb. 
	
	nadgrids=@conus,@alaska,@ntv2_0.gsb,@ntv1_can.dat

	* src/pj_grid*, src/pj_apply_gridshift.c, src/nad_init.c: Lots of
	changes introducing the PJ_GRIDINFO structure, support for skippable
	grids ('@' prefix), delayed grid data loading and support for NTv2
	grids. 

2003-03-16  Frank Warmerdam  <[e-mail]>

	*  Modified get_opt() to terminate reading the definition when a new
	definition (a word starting with '<') is encountered, in addition 
	to when the definition terminator '<>' is encountered, so that 
	unterminated definitions like those in the distributed esri file 
	will work properly.  Patch provided by Carl Anderson.

	* src/geocent.c: I have modified the Convert_Geodetic_To_Geocentric() 
	function to clamp Latitudes just a little out of the range
	-PI/2 to PI/2 and to no longer do error checks on Longitudes since
	they will be auto-wrapped by sin() and cos(). 

	See http://bugzilla.remotesensing.org/show_bug.cgi?id=17

	* nad/epsg: commited new updates with fixed units for us state plane
	zones in feet, as reported by Marc-Andre.

	mixed up.

	* src/proj.c: Generate an error message if +proj=latlong is used with
	this program.  As per bugzilla bug 70.

	* src/pj_init.c: call pj_open_lib() with mode of "rt" to ensure
	correct handling of def files on DOS based systems.
