. simplify the interface FrameBase to make it easier to implement it for different cases (remove HDC and make parameters more explicit)
. remove functions which are only called on a Win32Frame (in which case a cast is guaranteed to succeed)
. otherwise there is the risk that every FrameBase implementation wants to add its own variants.
. FrameBase::FrameRefreshStatus() simplify implementation: pass all flags explicitly
* Video / FrameBase: move arch specific code to FrameBase.
* Video::Initialize & SetFrameBuffer.
Ensure initialization and SetBuffer can only happen in the right order.
* Video: move virtual functions to FrameBase.
With these changes all the virtual functions are in FrameBase and Video gets closer to be (only) the Apple ][ Video device.
* Move a few more functions from Video to FrameBase (snapshot related)
Now, the inclusion is one way with Video *not* including FrameBase.
* FrameBase::VideoRefreshScreen move Video related code to Video.
And only leave management to FrameBase.
* WinVideo: move some generic functions back to Video.
Introduce a new virtual function (VideoPresentScreen) to draw the video buffer to video memory.
* Move Win32Frame::VideoRedrawScreen() to FrameBase as it is generic.
. class hierarchy: WinVideo IS_A Video (ie. WinVideo is a subclass of Video)
. GetVideo() singleton instance of WinVideo in AppleWin.cpp, exposed via Interface.h
* Interface.h: ensure that functions in the interface are not exported by other header files.
This is generally harmless, except for the presence of default arguments, in which case the version with default arguments must come first.
To avoid the issue, these functions are only ever exported in the Interface.h header file.
This is not complete as header files from Windows/.. are still included in:
Keyboard.cpp
SerialComms.cpp
Joystick.cpp
But probably these are arch specific and will have to be completely reimplemented elsewhere.
1. Newer VC runtime stat(), when using 32-bit file size, returns error
if file size is >2G. For file existence check, using 64-bit file
size is more accurate as files bigger than 2G would be reported as
non-existing otherwise.
2. <sys/stat.h> is required for VS2013 or before.
. Split AppleWin -> Core with the functionality really needed by the emulator.
. Split AppleWin -> Utilities for generic code not called by other emulator components.
. Split AppleWin -> CmdLine for the command line option parsing.
