fix for scrollbar segfaults
* fixes#206
* fixes broken mousewheel scrolling of the scenedit palette
* removed boost threads dependency
* added foundation for further refactoring of the drawing and event handling code: interfaces and drawable manager with layering
* removed a bunch of unneeded redraw calls
* removed some repeated recalculation of effectively constant values (boe.actions)
* removed recalculation of effectively constant scrollbar and button positions (boe.graphics)
Closes#251
This includes the following changes (mostly related to the above):
- Move loc_compare functor to location.hpp
- Add reattach() function to rebind a town or outdoor section to a different scenario object. (I don't think this is strictly necessary, as the scenario reference is only used in limited situations in the game itself, not in the editor, but it's better not to keep a reference to freed memory around when importing a town or sector from another scenario, even if the reference is never accessed.)
- Fix imported towns not being officially "loaded" until you explicitly use Load a New Town to reload them
- Fix Choose button in Load New Sector dialog
- More functions in the vector2d implementation
- You now specify your name instead of the scenario filename in the first dialog
- A file dialog pops up after the second dialog, to let you choose the filename and location
- Fixed using Warrior's Grove even if you chose not to
- Fixed not recognizing .EXS as a valid legacy-scenario extension and appending .boes, resulting in .EXS.boes
- Adjust Difficulty scenario flag set on by default
- You can copy/paste images into the sheet, or import/export to/from png files
Also:
- Picture controls in the dialog engine have a new "scaled" flag; if set, the picture will be scaled into the provided bounds rather than overflowing. Currently, only full sheets honour the setting.
