* Added Game::start() method which is called from DraciEngine::go()
* Made Game::loop() suitable for calling from other places (like GPL scripts) by handling events, redrawing the screen, etc from inside. This way it doesn't freeze the game if it doesn't return immediately.
* Added Game::shouldQuit() and Game::setQuit() which can be used to signal the engine to quit.
* Fixed race condition related to mouse buttons not getting released.
* Instead of deleting frames for the title animation and adding a new one, reset the text for its frame.
svn-id: r42875
* Trivial implementation of the Play GPL command
* Fixed Script::load() to load animation IDs to objects in increasing order (needed by funcActPhase())
svn-id: r42874
* Made GameObjects track their titles as Strings rather than byte *
* Made the engine display the title of the object under the cursor (added a special animation ID for that, kTitleText)
svn-id: r42839
* Added AnimationManager::getTopAnimationID(x, y) which returns the ID of the top layer animation located on a point
* Added Animation::getScale{X,Y}()
* Fixed a few bugs related to animations sometimes having no frames
svn-id: r42836
* Made Font::getStringWidth() calculate the width of the string properly now that handling of multi-row strings is in
* Fixed bug which caused the last column of pixels in the last letter of a string to linger on the screen
svn-id: r42832
* Added Text::drawScaled() and altered Text::getRect() so Text instances can be accessed through a Drawable pointer. Scaling text is planned for later because it's not essential.
svn-id: r42789
* Added support for setting loop status to Game.
* Made some GPL commands check whether we are in the correct loop status before executing.
svn-id: r42731
* Added Game::getNumObjects() which returns the number of objects in the game
* Fixed segfault (accessing a null Animation *)
* Added some docs to various things
svn-id: r42683
* Fixed bug in Animation::nextFrame() which caused non-looping animations to linger on forever
* Stopped setting looping to false explicitly in AnimationManager::addAnimation() since the Animation constructor already does that
svn-id: r42657
* Instead, Animation::nextFrame() marks both the old and the new frame dirty. This makes it possible to only update the real screen when the animation changes and results in a pretty big speedup.
* Added utility method Animation::markDirtyRect() which takes a (Surface *) and marks a dirty rect on it for the current frame.
* Fixed artifacts when moving the dragon.
svn-id: r42652
* Now each Sprite (and hence frame in an animation) can have a separate zoom (which is needed for some animations in the game)
* Scale factors are not stored any more; instead, we only store scaled dimensions (since these are stored in the data files) and calculate the factors from those.
svn-id: r42647
* Made the dragon scale when it is in different parts of the room
* Added getters for relative coordinates (Animation::getRelativeX() and Animation::getRelativeY())
* Commented Game::loop() and Sprite::draw*() methods in more detail
svn-id: r42627
