This function renders an image as a bitmap or to the screen and
can clip the image. The bitmap is either supplied by the caller
or else is allocated by the function. The images can be drawn
transparently or opaquely. If EFI_HII_DRAW_FLAG_CLIP is set,
then all pixels drawn outside the bounding box specified by
Width and Height are ignored. If EFI_HII_DRAW_FLAG_TRANSPARENT

the image will be written directly to the output device
specified by Screen. Otherwise the image will be rendered to
the bitmap specified by Bitmap.
This function renders an image to a bitmap or the screen using
the specified color and options. It draws the image on an
existing bitmap, allocates a new bitmap or uses the screen. The
images can be clipped. If EFI_HII_DRAW_FLAG_CLIP is set, then
all pixels drawn outside the bounding box specified by Width and
Height are ignored. The EFI_HII_DRAW_FLAG_TRANSPARENT flag
determines whether the image will be drawn transparent or
opaque. If EFI_HII_DRAW_FLAG_FORCE_TRANS is set, then the image
will be drawn so that all ????off???? pixels in the image will
be drawn using the pixel value from Blt and all other pixels
will be copied. If EFI_HII_DRAW_FLAG_FORCE_OPAQUE is set, then
the image????s pixels will be copied directly to the
destination. If EFI_HII_DRAW_FLAG_DEFAULT is set, then the image
will be drawn transparently or opaque, depending on the
image????s transparency setting (see EFI_IMAGE_TRANSPARENT).
Images cannot be drawn transparently if Blt is NULL. If
EFI_HII_DIRECT_TO_SCREEN is set, then the image will be written
directly to the output device specified by Screen. Otherwise the
image will be rendered to the bitmap specified by Bitmap.
@param This A pointer to the EFI_HII_IMAGE_PROTOCOL
