Currently closing game while network thread is waiting for something is
very bug-prone, since network thread may resume during shutdown and
access partially destroyed client state.
Now if exit has been requested, the very first step would be semi-
graceful shutdown of network thread (via exception throwing). This may
in theory skip some cleanup in non-RAII code, but since game is shutting
down this does not matters much.
This logic applies to:
- shutting down while network thread is waiting for dialogs
- shuttind down while network thread waiting for animations in combat
- added compatibility method to Canvas to allow SDL_Surface access
- added drawBorder method to Canvas to replace CSDL_Ext method
- added drawColor method to Canvas to replace CSDL_Ext method
- minor changes to Tavern and Trade windows to adapt to new API
- Added EShortcut enumeration that contains all in-game shortcuts
- CIntObject::keyPressed now receive values from hotkey enumeration
- On keypress, SDL key code will be translated to shortcut ID
- Removed access to SDL key codes from most of engine
- Rect no longer inherits from SDL_Rect
- renamed vcmi functions that used SDL naming format
- moved all functions in SDL_Extensions file into CSDL_Ext namespace
- SDL_Rect is now used only by SDL_Extensions, all other code uses Rect
- refactoring of CBattleStacksController.cpp
- moved EAlignment enum to Geometries.h from CIntObject
- renamed EAlignment to ETextAlignment, to avoid conflict with good/evil
alignemt
- ETextAlignment is now enum class
- refactoring of CBattleFieldController code (except for 2 arcane
methods)
- introduced class CCanvas for encapsulated rendering surface
- battleint rendering is now partially done with CCanvas
- removed unused includes of CBitmapHandler
