 * $Log: mitab_feature_mif.cpp,v $
 * Revision 1.35  2008/09/23 14:56:03  aboudreault
 * Fixed an error related to the " character when converting mif to tab file.
 *
 * Revision 1.34  2008/09/23 13:45:03  aboudreault
 * Fixed bug with the characters ",\n in the tab2tab application. (bug 1945)
 *
 * Revision 1.33  2008/02/01 20:30:59  dmorissette
 * Use %.15g instead of %.16g as number precision in .MIF output
 *
 * Revision 1.32  2007/06/07 20:27:21  dmorissette
 * Fixed memory leaks when reading multipoint objects from .MIF files
 *
 * Revision 1.31  2006/01/27 13:44:44  fwarmerdam
 * fixed Mills.mif reading, crash at file end
 *
 * Revision 1.30  2006/01/26 21:26:36  fwarmerdam
 * fixed bug with multi character delimeters in .mid file
 *
 * Revision 1.29  2005/10/04 19:36:10  dmorissette
 * Added support for reading collections from MIF files (bug 1126)
 *
 * Revision 1.28  2005/10/04 15:44:31  dmorissette
 * First round of support for Collection objects. Currently supports reading
 * from .TAB/.MAP and writing to .MIF. Still lacks symbol support and write
 * support. (Based in part on patch and docs from Jim Hope, bug 1126)
 *
 * Revision 1.27  2005/10/04 15:35:52  dmorissette
 * Fixed an instance of hardcoded delimiter (",") in WriteRecordToMIDFile()
 * (patch by KB Kieron, bug 1126)
 *
 * Revision 1.26  2005/07/14 16:15:05  jlacroix
 * \n and \ are now unescaped internally.
 *
 * Revision 1.25  2003/12/19 07:52:34  fwarmerdam
 * write 3d as 2d
 *
 * Revision 1.24  2002/11/27 22:51:52  daniel
 * Bug 1631:Do not produce an error if .mid data records end with a stray ','
 * Treat tabs (\t) as a blank space delimiter when reading .mif coordinates
 *
 * Revision 1.23  2002/10/29 21:09:20  warmerda
 * Ensure that a blank line in a mid file is treated as one field containing
 * an empty string.
 *
 * Revision 1.22  2002/04/26 14:16:49  julien
 * Finishing the implementation of Multipoint (support for MIF)
 *
 * Revision 1.21  2002/03/26 01:48:40  daniel
 * Added Multipoint object type (V650)
 *
 * Revision 1.20  2002/01/23 20:31:21  daniel
 * Fixed warning produced by CPLAssert() in non-DEBUG mode.
 *
 * Revision 1.19  2001/06/25 01:50:42  daniel
 * Fixed MIF Text object output: negative text angles were lost.  Also use
 * TABText::SetTextAngle() when reading MIF instead of setting class members
 * directly so that negative angles get converted to the [0..360] range.
 *
 * Revision 1.18  2001/02/28 07:15:09  daniel
 * Added support for text label line end point
 *
 * Revision 1.17  2001/01/22 16:03:58  warmerda
 * expanded tabs
 *
 * Revision 1.16  2000/10/03 19:29:51  daniel
 * Include OGR StyleString stuff (implemented by Stephane)
 *
 * Revision 1.15  2000/09/28 16:39:44  warmerda
 * avoid warnings for unused, and unitialized variables
 *
 * Revision 1.14  2000/09/19 17:23:53  daniel
 * Maintain and/or compute valid region and polyline center/label point
 *
 * Revision 1.13  2000/03/27 03:33:45  daniel
 * Treat SYMBOL line as optional when reading TABPoint
 *
 * Revision 1.12  2000/02/28 16:56:32  daniel
 * Support pen width in points (width values 11 to 2047)
 *
 * Revision 1.11  2000/01/15 22:30:44  daniel
 * Switch to MIT/X-Consortium OpenSource license
 *
 * Revision 1.10  2000/01/14 23:51:37  daniel
 * Fixed handling of "\n" in TABText strings... now the external interface
 * of the lib returns and expects escaped "\"+"n" as described in MIF specs
 *
 * Revision 1.9  1999/12/19 17:37:14  daniel
 * Fixed memory leaks
 *
 * Revision 1.8  1999/12/19 01:02:50  stephane
 * Add a test on the CENTER information
 *
 * Revision 1.7  1999/12/18 23:23:23  stephane

 * Return regions as OGRMultiPolygons instead of multiple rings OGRPolygons
 *
 * Revision 1.3  1999/12/16 17:16:44  daniel
 * Use addRing/GeometryDirectly() (prevents leak), and rounded rectangles
 * always return real corner radius from file even if it is bigger than MBR
 *
 * Revision 1.2  1999/11/11 01:22:05  stephane
 * Remove DebugFeature call, Point Reading error, add IsValidFeature() to 
 * test correctly if we are on a feature
 *
 * Revision 1.1  1999/11/08 19:20:30  stephane
