lyx_mirror/src/insets/InsetSpace.cpp
Jean-Marc Lasgouttes 7f6f56f40a Get rid of Inset::setDimCache 
This helper method is used to set the inset dimension cache at metrics
time. However this is already done by the metrics code itself
(MathRow::metrics, TextMetrics::redoParagraph), so that there is no
need to do this same work again in a different place.

Also, InsetPhantom::metrics is removed, since it does not do anything
interesting.

This commit comes with a mild risk attached (it might be that some of
these calls were useful after all!), but all of this is fixable.
