All controls now store a reference to their direct parent,
whether it be the dialog itself or a container control.
Every dialog control now has a guaranteed parent, which abstracts away
the three possible types of parents (dialog, container, and plain window).
The control name is now stored in the control from the moment it is parsed from the XML.
This means that it's set before the parseContent function, though after parseAttribute.
This allows widgets to be positioned relative to other widgets.
Two dialogs have been converted to use relative positioning.
Also fix some issues with calculating the dialog rect.
- Refactor dialog format parameter management to use a single protected control function
- Format parameters "frame" and "frame style" merged
- Colour is now a first-class format parameter (though it still has a separate setter)
This commit only updates the XCode project for the changes.
A later commit each will update it for scons and MSVC.
A few actual changes are mixed in:
- Add a prefix header for a handful of common definitions
- Moved current_cursor into the Cursor class as a static member
- Removed the make_cursor_sword and make_cursor_watch functions
- Include tests in the All target
- Remove redundant -l flags for Common and Common-Party (since they're included in the Link phases anyway)
