* InsetBase and all derivates: - metrics(MetricsInfo & mi, Dimension & dim) now returns a bool (true if metrics changed). * MathData and all derivates: - metrics(MetricsInfo & mi, Dimension & dim): ditto. * RenderBase and all derivates: - metrics(MetricsInfo & mi, Dimension & dim): ditto. * lyxtext.h/text.C: - LyXText::metrics(MetricsInfo & mi, Dimension & dim): ditto. - LyXText::redoParagraph(): take into account potential change in inset metrics. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@16091 a592a061-630c-0410-9148-cb99ea01b6c8
