Changed the readRect() method so it correctly adds one more pixel to the width and height. Fixed a couple of off-by-one errors in the viewport scrolling code. Set the menu and help buttons as transparent to avoid drawing green lines when they're pressed.
The Vampire Diaries' videos are all upside down after decompression, need a palette to be loaded from a separate bitmap file, and background videos are also quarter size (1/2 width and height). This commit adds a GraphicsManager function for loading a Surface or a raw buffer into a ManagedSurface, applying all transformations needed to display it correctly.
Added generic methods for getting the pixel format and transparent color. Also added a method for loading an image directly into a ManagedSurface, which also loads the palette and lets The Vampire Diaries logo display properly.
Made all states (Scene, Credits, Help, etc.) singletons, as well as subclasses of a common State parent with a proper state switching API. Moved the OnPause virtual function from RenderObject to ActionRecord and hooked it into the state switching code. Also got rid of the NancyEngine pointer that got passed around between most classes, and replaced it with several convenience macros. As a result of these changes action records that render to the viewport no longer disappear after opening the menu, and state changes feel snappier.
Implemented the button on the map screen that returns the player to the last scene, as well as the secret button in the same position that teleports the player to the map from select few scenes.
Fixed an issue where movement wouldn't work correctly if the user clicks the viewport edges several times in quick succession instead of clicking and holding.
Rewrote most of the engine using a much more object-oriented approach and using more of ScummVM's common classes. This design deviates quite a lot from the original engine's, but should be more maintainable and extensible in the future.
