Routine Description:
This function is DLL main entry point, at here we will save the module handle, in the future we will need to do other initialization stuff.
Arguments:
hModule - Handle to this moudle when get loaded.
Reason - may be DLL_PROCESS_ATTACH
Reserved - reserved
Return Value:
Always return 1L

/*++
Routine Description:
This is the API entry for the halftone color adjustment, this function only allowed adjust the input colors
Arguments:
pCallerTitle - Pointer to the caller's title, it can be application name, device name... which will be display in the dialog box 'modify for:' line, if this field is NULL then no title name is displayed on that line.
hDefDIB - If it is not NULL then this function will try to use this DIB as default picture to adjustment testing.
pDefDIBTitle - Pointer to a string which indified the test DIB content.
pColorAdjusment - Pointer to the COLORADJUSMENT data strcuture, this data structure will updated upon exit.
ShowMonochromeOnly - Only display mono version of the bitmap
UpdatePermission - TRUE if ok for user to change the COLORADJUSTMENT setting
Return Value:
LONG value
> 0 - If user choose 'OK' which the new data are updated into pColorAdjustment.
= 0 - If user choose 'CANCEL' which the operation is canceled
< 0 - An error occurred, it identified a predefined error code
