* only update the representation if anything was changed (this gives a huge speedup), fixes #2452 * minor cleanup of the code, especially setting up the coordinate cache. Without this can lead to crashes if the macros do not mention all the arguments. * And a last fix included makes sure that the metrics are always in sync with the drawing. Before it was possible to go into the macro with the cursor in a way that the metrics were for the viewing mode, but the drawing was done for editing. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@18489 a592a061-630c-0410-9148-cb99ea01b6c8
