The text in the various help dialogs that was previously baked into an image is now drawn as text, meaning that it benefits from text unblurring when scaling is active.
This entails some small changes to layout, since it's a different font.
Dialog engine changes:
* A new picture type allowing to draw the inventory button icons directly into a dialog.
* A new widget type that simply draws a line between two points.
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()
These were very shoddily put together!
It seems the person who made them never really tried building
the editors or the tests.
Also included here are a couple of minor source changes that are needed
to make the project files build.
