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.
Fixed the visual artifacts in the inventory box curtains in The Vampire
Diaries. Renamed the Shades class to Curtains to reflect their name in
the original engine.
Moved all hardcoded engine data that changes between games (e.g. number
of items, number of event flags) to a dedicated file and added a function for
accessing it in NancyEngine.
Changed the UI::Scrollbar class so it doesn't require subclassing and added functionality for horizontal scrollbars. Fixed the textbox and inventory box scrollbars so their lowest point is consistent with the original engine's.
SoundManager is now responsible for loading and storing all common sounds (sounds with their own BOOT chunk). All playSound() calls with a hardcoded channel ID now use the chunk name instead. Also fixed some sound inaccuracies when switching between states.
Added a \0 to every instance of a char buffer being loaded into a Common::String. Fixed an instance of a large buffer getting repeatedly allocated and deleted inside a for loop. Fixed an instance of a small char buffer being unnecessarily allocated on the heap. Also added a readFilename() convenience function to util.h for reading 8-character filenames found in the data.
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.
The resource manager now keeps track of its cif trees and calls to loadImage() and loadData() don't need to specify a cif tree. In order to support The Vampire Diaries, IFFs can now be loaded from their own dedicated .iff file, and the engine doesn't require a cif tree to be loaded on boot.
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.
Added initial support for savestates. The format will most likely change with future commits, but I will only start versioning once the engine supports more than a single game. To support proper serialization the Scene state has had its kInit state split into kInit and kInitStatic, InventoryBox had some of its code reordered, and members of several classes have had their types changed.
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.
