1.1     ! root        1: Sample: PlgBlt Demonstration
        !             2: 
        !             3: Summary:
        !             4: 
        !             5: Win32 offers a new API function that will copy a bit image
        !             6: onto an arbitrary parallelogram. Now, for the first time,
        !             7: application programs can trivially rotate or shear bitmaps.
        !             8: The PLGBLT SDK sample is an easy to use demonstration of how
        !             9: this new API function may be used.
        !            10: 
        !            11: More Information:
        !            12: 
        !            13: The program presents a dialog box on top of the window that
        !            14: displays the input parameters to the PlgBlt function. By
        !            15: choosing the "New Src" or "New Mask" button, the user can
        !            16: select a new bitmap for use as the source bitmap or as the
        !            17: monochrome mask bitmap. The client area of the window is
        !            18: divided into three regions. The region on the left contains
        !            19: the result of the PlgBlt operation. The region in the middle
        !            20: provides the source HDC, and the region on the right
        !            21: provides the mask bitmap for the PlgBlt operation.
        !            22: 
        !            23: In each of the three regions, there is a "direct
        !            24: manipulation object." This object may be picked up and moved
        !            25: by clicking the left mouse button in the top-left corner and
        !            26: dragging. The three objects are restricted in their response
        !            27: to user actions to correctly reflect the parameters to the
        !            28: PlgBlt function. The object in the mask region may be moved
        !            29: only. The object in the source region may be moved or sized.
        !            30: The object in the destination region may be moved, sized,
        !            31: sheared, or rotated. Please see the WXFORM sample for more
        !            32: information on how this direct manipulation is accomplished.
        !            33: Additional information on the WXFORM sample may be obtained
        !            34: by querying on the word WXFORM in this knowledge base.
        !            35: 
        !            36: The following is a list of the Win32 API functions used in
        !            37: this sample:
