The Russian translations of nancy5 and up (except for
nancy6) switched to a Windows-1251 encoding for their
strings, and changed up the format of the FONT chunks.
Fixed (hopefully) all issues with color changes in text being
in incorrect positions. The new algorithm ignores all
whitespace characters when counting how much has been
drawn on screen, as they, combined with word wrapping,
were the source of the miscounting.
Fixed some incorrect assumptions about the data found
inside TBOX and FONT boot chunks. Made relevant changes
to HypertextParser to reflect the new data.
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.
