Subject: Support all xymatrix arguments
X-Git-Tag: 1.6.10~12119
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=f8b9d95ee407c7867692f7e56b4ff06274463b58;p=features.git

Support all xymatrix arguments
	* src/LaTeXFeatures.C
	(LaTeXFeatures::getPackages): Add package xy

	* src/mathed/InsetMathXYMatrix.[Ch]
	(spacing_): New
	(spacing_code_): New
	(validate): New, require xy package

	* src/mathed/InsetMathXYMatrix.C
	(InsetMathXYMatrix::write): write spacing_ and spacing_code_
	(InsetMathXYMatrix::infoize): output spacing_ and spacing_code_

	* src/mathed/MathFactory.C
	(createInsetMath): handle special arguments of xymatrix

	* src/mathed/MathParser.C
	(Parser::parse1): ditto
