Behaviorally: This change makes it so that Enter will never cancel
a dialog, unless that dialog only contains info to be read. Escape
will never unpredictably be treated as Enter. And some dialogs without
Escape to cancel, now can be canceled with Escape.
A lot of this just refactors dialogs to define the cancel button
at the top, not as a hotkey on a cancel button deep in the XML.
I think this makes enter/escape behavior in dialogxml files more
legible at a glance.
I'm planning to make it so the Enter key will never cancel a yes/no dialog. To do this, I'm adding an Escape button to dialogs. So cancel/accept keyboard shortcuts will be predictable and intuitive. Dialogs that require extra confirmation will have a 'really confirm' LED.
Search field starts out hidden. When the button is
clicked, the field and other controls appear, and
the button takes over the enter key. Ctrl+Enter
clicks okay (so if search is not opened, either
Enter OR Ctrl+Enter will click okay)
* The rightmost column is now mostly dedicated to non-modifying operations – eyedropper and zoom are moved there, pushing the 3 palette buttons down in town mode.
* Set Starting Location and Set Town Boundaries moved from the menus into the toolbar.
* Place Same Creature and Place Same Monster removed, since placing a monster or creature no longer resets the mode, so you can place as many of the same one as you like.
* Erase Town Entrance removed – what is it even good for? Removing the entrance without removing the town terrain is nonsensical. A town entrance can now be erased just by painting over it.
* Copy Item, Copy Monster, and Copy Terrain added. The latter copies a rectangle of terrain.
* Paste Special is removed. Instead there's a generic Paste button which pastes whatever type of thing you copied last, whether it be a special, a monster, an item, or even some terrain.
* Horse and boat no longer share a row with road. Instead, some of the fields have been reshuffled, so now fields take up three rows (though not three complete rows)
It now makes no assumptions about the terrains that might be defined in the base scenario.
* The existing terrain in the base's outdoors (previously ignored entirely) is now partitioned into 9 segments and plopped down to form the border of the new scenario's outdoors.
* It treats the locations (23,23) amd (24,24) specially, assuming they contain a sign and a town respectively. These are left as-is in the top left sector but replaced with the base ground in every other sector.
* Since there are now two separate bases, one for cave and one for surface, no substitution of terrain is done in the starter town.
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.
