comparison base/PropertyContainer.cpp @ 46:5364a9d338a2

* Add Insert Instant function in main window
* Ensure selections and window geometry are saved in session file
* Add wait cursor on session file save
* Various improvements to display of texts in pane (clearer readability)
* Use commands for setting properties on layers and panes
  (still need to batch up multiple sets on the same property)
* Fix failure of spectrogram to refresh when initial part became visible
* Some fixes & paint optimisations in View &c
* Make curve mode for time value layers work properly when resolution == 1
* Some vague improvements for time value layer vertical scale

     
     This is experimental software.  Not for distribution.
