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.
Removed the BlitType enum and getBlitType() method from RenderObject, and replaced them with setTransparent(). This was done to reduce redundant code, since ManagedSurface can already pick between a transparent and regular blit depending on whether the provided source surface has a transparent color set. Also added the correct transparent color for The Vampire Diaries, and the transparent color for nancy1 now gets calculated on the fly.
Changed surfaces in the textbox and inventory box so they are now initialized with the screen pixel format instead of the one used inside images. With this change The Vampire Diaries no longer fails a particular assert in the ManagedSurface blitting code, and can now boot successfully.
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.
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.
Implemented most of the PlayPrimaryVideoChan0 action record, which is used in all dialogue and the intro cutscene. For now the audio and video are out of sync, the scrollbar doesn't work, and the mouse isn't constrained.
Added the place names that appear when hovering a location on the map screen and the button to return to the last scene. Also made some minor improvements to the input manager.
Implemented the map state, as well as the two main action record types that call it. Also made some minor related changes to the scene and graphics managers.
Implemented the PlaySecondaryMovie action record, which is used in some death scenes. Also made some minor changes to a few other action records and the sound manager.
Implemented PlayIntStaticBitmapAnimation, which allows the teacher's room PC screensaver to display properly. This impementation skips the sound component, which will be added later if needed.
Implemented the two SecondaryVideo channels, allowing the game to display NPC animations outside of dialogue. The implementation repeats some frames and plays at the wrong speed so further work is needed.
