The picker is used in the special node dialog and also in monster abilities.
Some changes were made to the game as well:
* If the rotatable wall is used for a field missile or touch ability, there's no longer an option for the designer to pick an orientation. Instead, it behaves like the rotatable wall in a radiate field ability, selecting an orientation based on the creature's facing direction.
* The magic values sent to place_spell_pattern for direct damage were rearranged to match the order of the eDamageType enum. This should have no effect, since the core place_spell_pattern function is only called by the various wrapper overloads. It also simplifies the code quite a bit.
* The Protective Circle spell pattern is now exposed to the place patten special nodes. It can be used as just a radius 4 circle, but the effect of different layers of fields can also be obtained by specifying a field type or damage type of -1.
There is also a change to the dialog engine:
* Calling setText() also implicitly calls recalcRect()
The limit of 3 saved item rectangles has been removed - you can now add as many as you want.
However, the 1 per town limit is now strictly enforced.
The saved item rectangle is now shown with a cyan border when editing town.
These are the rules:
- If the active PC gets an empty shop, iterate from the first to last PC until finding someone who can see a shop item
- If none can shop, show the 'no item' response
- When the active PC buys something, if this clears out the shop, iterate from the first to last PC until finding someone who can see a shop item
- if none can see an item, stay on the empty shop of the PC that was active when the last item was bought.
- When shopping ends, if the shop interface was the last thing to change the player's active PC, it puts it back how it was.
Fix#669
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.
