	* math_xiter.h: remove a couple of "inline"

	* array.C (strange_copy): fix bug (hopefully)
	* many files: add a lot of new files and move methods to the class
	files they belong to. Only first attempt at cleanup more will
	follow.

2001-02-12  Andr<64> P<>nitz  <poenitz@gmx.net>

	* math_macro.[hC]: replace MathMacroArgument[] with
	  std::vector<MathMacroArgument>
	* math_defs.h:
	  math_inset.C: replace int[] with std::vector<int>
	* math_panel.h:
	* math_symbols.C: replace FL_OBJECTP[] with
	std::vector<FL_OBJECT*>

2001-02-12  Lars Gullik Bj<42>nnes  <larsbj@lyx.org>

	* math_defs.h (struct MathedRowSt): make all private variables end
	with '_', initialize in initializer list instead of in function
	body.

2001-02-12  Dekel Tsur  <dekelts@tau.ac.il>

	* formula.C (LocalDispatch): Change the default action of
	break-line to create an align* environment instead of eqnarray*.

	* math_inset.C (Metrics): Correct drawing of the multline
	environment.

2001-02-12  Andr<64> P<>nitz  <poenitz@gmx.net>

	* array.[hC]: replace private variable maxsize_ with call to
	bf_.size()
	* math_defs.h: replace int[] by std::vector<int> for
	MathedRowSt::widths

2001-02-09  Lars Gullik Bj<42>nnes  <larsbj@lyx.org>

	* array.h: made all variables private, removed friend, added new
	methods: raw_pointer_insert, raw_pointer_copy, strange_copy, added
	non const operator[] added setter for last and getter for maxsize.
	changed name from LyxArrayBase to MathedArray.
	changed name of some methods to start with lowerchar.
	moved inline methods to array.C

	* math_iter.C + several file: changes because of the above.

	* array.C: new file with the prev inline methods.

2001-02-10  Dekel Tsur  <dekelts@tau.ac.il>

	* Many files: add support for the align environment from amsmath.

2001-02-09  Andr<64> P<>nitz  <poenitz@gmx.net>

	* array.h: replace array buffer  'byte bf[]'  by 'std::vector<byte> bf'
	* several files: subsequent changes
	* math_iter.h: remove unused prototype
	* array.h: ditto.

2001-02-08  Jean-Marc Lasgouttes  <Jean-Marc.Lasgouttes@inria.fr>

	* math_macro.C (draw): add .c_str() to .str() (useful when
	compiling with lyxstring, but STL sstream).
	(Metrics): ditto.

2001-02-08  Andr<64> P<>nitz  <poenitz@gmx.net>

	* several files: get rid of reinterpret_cast.

2001-02-04  Allan Rae  <rae@lyx.org>

	* math_parser.C (mathed_parse): I'm sure Lars has a better fix than
	just casting the variable.

2001-02-02  Dekel Tsur  <dekelts@tau.ac.il>

	* Many files: Add support for multline and alignat environments from
	amsmath.

2001-02-02  Dekel Tsur  <dekelts@tau.ac.il>

	* math_symbols.C (math_insert_greek): Move cursor right when
	unlocking the math inset.

2001-01-26  Dekel Tsur  <dekelts@tau.ac.il>

	* math_parser.C (LexGetArg): Fix crash when loading corrupt files.

	* formula.C (LocalDispatch): Before inserting a label in an
	eqnarray, move the cursor to the top level.

	* math_iter.C (getLabel): Test if crow == 0.

2001-01-15  Dekel Tsur  <dekelts@tau.ac.il>

	* math_draw.C (Metrics): Use the correct GetString.
