lyx_mirror/src/insets/insetcharstyle.C
Abdelrazak Younes e24bf64c68 * dimension.h: new operator!=() and operator=()
* 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.
