Rewrote GraphicsManager::draw() to be simpler and more correct,
eliminating the need for RenderObjects to know what they're
overlapping at creation. This comes at the cost of slightly increased
redraw, but that can be reduced fairly easily if needed.
Added a compressed variant of the Russian translation of Nancy Drew:
Secrets Can Kill. Added a flag to mark compressed game variants and
only load archives when playing one. Removed the 8-bit colors flag.
Replaced most calls to getBasePtr() inside GraphicsManager::copyToManaged() with simpler pointer arithmetic to make it less costly when copying double size images.
Did some cleanup of the engine, mostly focusing on the NancyEngine class. Reordered several classes' members, removed unused functions, edited comments, and renamed arfactory_v1.cpp to arfactory.cpp.
Removed some leftovers from an older version of the graphics manager and made the drawing code only loop once through all render objects instead of twice.
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.
Action records are no longer expected to return how much data they've read, which will be helpful with supporting different versions in the same class. Also added a much more helpful error message on a bad read.
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.
Changed the readBootSummary function so it uses a serializer with the game type enum as its version. With this change, we don't need separate subclasses just to read every different BSUM format, so all of the NancyEngine child classes have been removed.
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 finishExecution function, which allows some action records with the correct execType to restart after they've been triggered. Since this can result in objects getting added to the graphics manager twice, also added checks to the addObject function to avoid duplicates.
Fixed an issue where RenderObjects would get registered twice in the graphics manager and sometimes cause a segmentation fault when closing the interpreter.
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 code to move the two scrollbars and implemented renderFrameInvBox(), which displays the inventory. Actually populating the inventory and interacting with it are still TODO.
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.
Implemented a simple mouse with the ability to change the cursor bitmap. Also changed the View struct to use Rects instead of separate properties for every coordinate.
