/*************************************************************************
*
* Name : WinProc(hwnd, msg, mp1, mp2)
*
* Description: Processes the messages sent to the main client
* window. This routine processes the basic
* messages all client windows should process.
*
* Concepts : This procedure provides service routines for the general
* PM events (messages) that PM sends to the window, as well
* as the user initiated events (messages) that are generated
* when the user selects the action bar and pulldown menu
* controls or the corresponding keyboard accelerators.
*
* The switch statement shown below distributes the window
* messages to the respective message service routines, which
* are set apart by the case statements. The window
* procedures must provide an appropriate service routine for
* its end user initiated messages, as well as the general PM
* messages (like the WM_CLOSE message). If a message is sent
* to this procedure for which there is no programmed case
* clause (i.e., no service routine), the message is defaulted
* function WinDefWindowProc, where it is disposed of by PM.
*
* Time-consuming tasks are posted to the object window where
* they can be performed without the 1/10 second turnaround
* time imposed on the client window. When the object window
* is busy, the client window is usually disabled. The object
* window then posts an acknowledgement
* back to the client when the lengthy task is completed.
*
* Cases under the big switch appear in alphabetical order.
*
* API's : WinLoadString
* WinMessageBox
* WinQueryWindowULong
* WinSendMsg
* WinPostMsg
* WinIsWindowEnabled
* WinSetPointer
* WinQuerySysPointer
* WinBeginPaint
* WinQueryWindowRect
* WinFillRect
* WinEndPaint
* WinInvalidateRect
* WinSetWindowText
* GpiDrawChain
* GpiConvert
* GpiSetDefaultViewMatrix
* GpiAssociate
* GpiDestroyPS
* GpiDeleteBitmap
* GpiDeleteMetafile
*
* Parameters : HWND window handle
* ULONG message
* MPARAM message parameter 1
* MPARAM message parameter 2
*
* Result : MRESULT message result
