Creates a \c HBITMAP equivalent to the QPixmap. Returns the \c HBITMAP
handle.
If \a mask is not NULL, the mask mode is turned on. In this mode, the bitmap
mask is also created from the QPixmap's mask and returned in the given
variable. This bitmap mask will contain two vertically adjacent sections,
the first of which is the AND mask and the second one is the XOR mask
(according to WinCreatePointer() specification). Also, in mask mode, the
HBITMAP returned for the pixmap itself will be prepared for masking (with
transparent pixels made black). This mode is useful for creating system
icons and pointers (\sa toPmHPOINTER()).
if \a embedRealAlpha is \c true, the real alpha chennel (not the 1bpp mask)
will be embedded in the high 8 bits of the 32-bit pixel value for each pixel
in the created bitmap (which always has 1 plane and the 32-bit depth). This
extra information isn't touched by PM/GPI but may be used by custom drawing
routines to do real alpha blending.
Note that if \a mask is not NULL but the pixmap does neither have a mask nor
the alpha channel, an emptpy bitmap mask with no transparency (zeroed AND
and XOR parts) will be created and returned.
It is the caller's responsibility to free both returned \c HBITMAP handes
after use.
