* Implemented GPL commands Script::loadMap() and Script::roomMap().
* Added temporary HACK to change some speech texts to use the small font because some strings overflow the screen (as stored in the data files).
svn-id: r43161
* Extracted title updating from the main loop to a new method, Game::updateTitle().
* Added Game::updateCursor().
* Restructured the main loop to fix many subtle bugs and enable some new functionality concerning object scripts (like support for room-global use scripts).
* Added support for tracking currently selected icons (items, probably should be renamed).
* Changed walkDir, lookDir and useDir members of GameObject to int and adjusted them for zero-based indexing.
* Added Game::getCurrentIcon().
* Return from WalkingMap::findNearestWalkable immediately if the starting point is walkable.
svn-id: r43160
* Added enum constant kNoEscRoom for rooms that have no escape room defined
* Fixed crash when ESC is pressed in rooms which have no escape room defined
* Renamed kNotFound (used as a return value for Game::getObjectWithAnimation) to kObjectNotFound for clarity.
svn-id: r43072
* Reworked the left and right arrow key commands so they don't call changeRoom() themselves but instead schedule the room change via Game::setRoomNum(). In this way, changing rooms like that is still a hack but a bit more "natural", since the loop doesn't get skipped, the gate scripts get run, etc.
svn-id: r43065
* Handled title positioning
* Cleaned up the main loop a bit (comments, stylistic changes, shortened some lines, etc)
* Fixed setting the dragon's feet position (the x coordinate should be at the midpoint of the animation)
svn-id: r43059
* Changed Font::getStringWidth() and Font::getStringHeight() to return uint instead of int.
* Made the Font::drawString() overload which accepts a Common::String the "default" one. The overload accepting a (byte *) now calls that one (it was the other way around before).
* Added proper line centering to the Font::drawString() routine.
svn-id: r43053
* Handled the kStatusTalk loop substatus properly inside Game::loop().
* Made Game::walkHero() set the person coordinates for the dragon after it warps him to a new location
* Added Game::getPerson() method (used by Script::talk())
* Added Game::setSpeechTick() method (set by Script::talk() and used inside the loop to determine when to switch to new text).
svn-id: r42994
* Added a separate mechanism to Game to keep track both of the current room number and the next room/gate. Periodically, I check whether the new room differs from the old one and, if it does, I do the change. Doing it any other would is nearly impossible because of the way the original scripts were written.
* Added GPL command Script::newRoom(). Rooms can now be traversed by clicking on their exits. Also, the intro animation partly works. Some parts go by far too soon. I assume this is because the engine still lacks a dialogue GPL command.
* Fixed bug where the gates array of a room was not cleared between uses.
* Save old jump value when we enter Script::run() and restore it in the end (mimicking the original engine).
* Fixed small bug where the gate was supposed to be stored as the first in-game variable and not the room number.
