Functions
void	sys_init (HINSTANCE hInst, int width, int height, int colorDepth, bool fullScreen)
	setup the AEngine. You should call this before doing anything else hInst is passed to you by WinMain. Just pass it along to this function note that not all modes can be supported by your video card try standard things such as 800x600x16bit or 1024x768x32bit
void	sys_setSkipRate (int rate)
	rate=0 means try never to skip any frame. rate=1 means render every other frame
void	sys_setInitFunc (AierraInitFunc f)
	set call-back functions so the engine knows how to init, update the game state, render it, and shut down
void	sys_setUpdateFunc (AierraUpdateFunc f)
void	sys_setRenderFunc (AierraRenderFunc f)
void	sys_setShutdownFunc (AierraShutdownFunc f)

void	createWindow ()
void	findCompatibleMode (D3DDISPLAYMODE &d3dDisplayMode)
void	createRenderingDevice ()
void	sys_shutdown ()
void	displayLoadingScreen ()
void	sys_go ()
	let the program runs. This function doesn't return (until sys_terminate())
void	sys_terminate ()
	terminate the application. This function never returns
void	sys_showFPS (bool show)
	whether to show the frame rate in the top-right corner
void	sys_showConsole (bool show)
	whether or not to display the console window
void	sys_enableConsoleLog (string filename)
	this function must be called before sys_go(); this will log all subsequent output to the console to the specified logfile
ostream &	sys_console ()
	this returns you an output stream that you can write stuffs to they will be displayed on the in-game console window if it is set to visible
void	sys_flushConsole ()
	flushes all texts sent to consol eto log file (if any)
void	sys_fastForwardUpdate (int times)
	quickly update the game state 'times' times. this is quivalent to fast forwarding the game by roughly 'times'/62.5 seconds
DWORD	sys_getMilliSec ()
	get current time in ms
void	sys_setRandSeed (int seed)
	use these functions instead of the builtin rand, srand so we can log and keep track of what's going on
