+ The Helio Emulator emulator (source is available) uses the depreciate
+ SetBitmapBits() function, what probably exposes an error in our DIB handling.
+ 
+ First a 4 bit DIBSection is created:
+     lpbi->bmiHeader.biPlanes = 1;
+     lpbi->bmiHeader.biBitCount = 4;
+ ..
+     PVOID pvBits;
+     m_hbmLCD = CreateDIBSection(hdc, lpbi, DIB_RGB_COLORS, &pvBits, NULL, 0 );
+ 
+ Later the real data is set:
+     HDC hdcLCD = CreateCompatibleDC(hdc);
+     HBITMAP hbmOld = (HBITMAP) SelectObject(hdcLCD, m_hbmLCD);
+     SetBitmapBits(m_hbmLCD, LCD_WIDTH*LCD_HEIGHT/2, m_abLCDBits);
+     StretchBlt(hdc, m_rcScrn.left, m_rcScrn.top, cxScrn, cyScrn, hdcLCD, 0, 0,
+ LCD_WIDTH, LCD_HEIGHT, SRCCOPY);
+     SelectObject(hdcLCD, hbmOld);
+     DeleteDC(hdcLCD);
+ 
+ Now the four bit data given is handled as 24 bit data which was used for the
+ bitmap during CreateDIBSection and the display is wrong. I think we need to use
+ SetDIBits somehow, but I don't know how.
+ 
+ Bye
