////////////////////////////////////////////////////////////////////
// To save the image of a window to a BMP file, you have to draw the image
// to a compatible memory device context, convert the bitmap associated with
// the memory DC to a device-independent bitmap and then write the DIB to a file.
//	In previous sections, we have already covered how to get a DIB from a 
// device-dependent bitmap and how to save a DIB to a file. The WriteWindowToDIB()
// function uses the DDBToDIB() and the WriteDIB() functions to accomplish its task.
//	  However, this is just half of the job; the other half is to get the logical
// palette that can be used with the bitmap. The bitmap won't display properly if
// it needs a logical palette and one is not available. Depending on the display 
// settings we don't always need a logical palette. We use GetDeviceCaps() to determine
// whether a display device supports palette operation. For instance, if the display is 
// set for true color then it doesn't support a palette. We allocate enough memory for a
// LOGPALETTE structure and then use the GetSystemPaletteEntries() to fill the color table.
// Now we can create the logical palette.
//	  The function then uses the DDBToDIB() and the WriteDIB() functions to complete the job.
// You should note that if the window is partially or completely covered by other windows then
// the saved bitmap will show parts of these other windows too.

//
// A device-dependent bitmap (DDB) is structured in such a way that it matches 
// very closely the form in which the bitmap is finally displayed by the device driver.
// For this reason the DDB is unlikely to be compatible with other display devices.
// A device-independent bitmap (DIB) on the other hand has a logical layout and can be
// decifered by any device driver. The disadvantage with DIB though is that it is much 
// slower to render onto the device as compared to a DDB.
//
// One situation where we need to convert a DDB to a DIB is when we want to save the bitmap
// to a file. The BMP files are infact just composed of a short header followed by
// information in a DIB.
//
// The steps involved in creating the DIB are:
//   1. Initialize a BITMAPINFOHEADER data structure. We use information in the bitmap 
//	  to determine the widht, height and the bit count. The compression field is set 
//	  based on the argument passed into the function. It's best to use the BI_RGB 
//	  compression for greater portability and faster rendering.
//   2. Select and realize the logical palette associated with the bitmap. This 
//      is passed in as the last argument to the function. If a palette is not provided 
//	  use the default palette.
//   3. Determine the number of bytes required for the bitmap bits. First allocate 
//      enough memory for BITMAPINFOHEADER and the color table and then call GetDIBits() 
//	  to size. Supplying a NULL for the lpBits parameter instructs GetDIBits() to 
//	  biSizeImage field in the bitmapinfoheader. Sometimes, this does not work 
//	  (depending on the device driver) in which case we make our own estimate. 
//	  We can compute this since we already know the width, height, the number of bits 
//	  per pixel and the fact that each row of pixels will occupy a multiple 
//	  of 4 bytes (32 bits).
//   4. Given the final size of the bitmap bits, reallocate the memory block to hold
//      the bitmapinfoheader, the color table and the bitmap bits.
//   5. Finally call the GetDIBits() again to get the bitmap bits.

// History - 10/3/97 Fixed scrolling bug.
//                   Added print support. - KR
//
//           11/3/99 Fixed most common complaint. Added
//                   background color fill. - KR
//
//           11/3/99 Added support for mapping modes other than
//                   MM_TEXT as suggested by Lee Sang Hun. - KR
//
//           02/11/02 Added support for CScrollView as supplied
//                    by Gary Kirkham. - KR
//
// This class implements a memory Device Context which allows
// flicker free drawing.
 
// Changed by Matthias Pospiech (2007) with additional support 
// of stretching a bitmap onto a dc.
