// dibapi.cpp
//
// Source file for Device-Independent Bitmap (DIB) API. Provides
// the following functions:
//
// PaintDIB() - Painting routine for a DIB
// CreateDIBPalette() - Creates a palette from a DIB
// FindDIBBits() - Returns a pointer to the DIB bits
// DIBWidth() - Gets the width of the DIB
// DIBHeight() - Gets the height of the DIB
// PaletteSize() - Gets the size required to store the DIB‘s palette
// DIBNumColors() - Calculates the number of colors
// in the DIB‘s color table
// CopyHandle() - Makes a copy of the given global memory block
//

*
* PaintDIB()
*
* Parameters:
*
* HDC hDC - DC to do output to
*
* LPRECT lpDCRect - rectangle on DC to do output to
*
* HDIB hDIB - handle to global memory with a DIB spec
* in it followed by the DIB bits
*
* LPRECT lpDIBRect - rectangle of DIB to output into lpDCRect
*
* CPalette* pPal - pointer to CPalette containing DIB‘s palette
*
* Return Value:
*
* BOOL - TRUE if DIB was drawn FALSE otherwise
*
* Description:
* Painting routine for a DIB. Calls StretchDIBits() or
* SetDIBitsToDevice() to paint the DIB. The DIB is
* output to the specified DC at the coordinates given
* in lpDCRect. The area of the DIB to be output is
* given by lpDIBRect.
