Routine Description:
This function determined the RGB primary order from the RGB bit fields
Arguments:
pBFInfo - Pointer to the BFINFO data structure, following field must
set before the call
BitsRGB[0] = Red Bits
BitsRGB[1] = Green Bits
BitsRGB[2] = Blue Bits
BitmapFormat = BMF_16BPP/BMF_24BPP/BMF_32BPP
RGB1stBit = Specifed PRIMARY_ORDER_xxx ONLY for BMF_1BPP,
BMF_4BPP, BMF_8BPP, BMF_24BPP
requested order.
Return Value:
FALSE if BitsRGB[] or BitmapFormat passed are not valid
else TRUE and following fields are returned
BitsRGB[] - corrected mask bits
BitmapFormat - BMF_16BPP/BMF_24BPP/BMF_32BPP
Flags - BFIF_xxxx
SizeLUT - Size of LUT table
BitStart[] - Starting bits for each of RGB
BitCount[] - Bits Count for each of RGB
RGBOrder - Current RGB order, for BMF_1BPP, BMF_4BPP, BMF_8BPP
and BMF_24BPP the RGBOrder.Index must specified a
PRIMARY_ORDER_xxx, for BMF_16BPP, BMF_32BPP the
RGBOrder.Index will be set by this function
RGB1stBit - The bit start for first on bit in BitsRGB[]
GrayShr[] - The right shift count so that most significant bit
of each RGB color is aligned to bit 7 if the total
bit count of RGB is greater than 8 otherwise this
value is 0, it is used when construct the monochrome
Y value.

ComputeBytesPerScanLine(

/*++
Routine Description:
This function calculate total bytes needed for a single scan line in the
bitmap according to its format and alignment requirement.
Arguments:
SurfaceFormat - Surface format of the bitmap, this is must one of the
standard format which defined as SURFACE_FORMAT_xxx
AlignmentBytes - This is the alignment bytes requirement for one scan
line, this number can be range from 0 to 65535, some
common ones are:
0, 1 - Alignment in 8-bit boundary (BYTE)
2 - Alignment in 16-bit boundary (WORD)
3 - Alignment in 24-bit boundary
4 - Alignment in 32-bit boundary (DWORD)
8 - Alignment in 64-bit boundary (QWROD)
WidthInPel - Total Pels per scan line in the bitmap.
Return Value:
The return value is the total bytes in one scan line if it is greater than
zero, some error conditions may be exists when the return value is less
than or equal to 0.
Return Value == 0 - The WidthInPel is <= 0
Return Value < 0 - Invalid Surface format is passed.

Fixing bug for alpha blending, in gray scale mode, the destination
can only be 1bpp or 8bpp mask mono, so when we read back from the
destination to do alpha blending, it will double color mapping pixels.
In gray scale mode, the input function will map the source RGB value
to gray value with the current device transform, color adjustment and
so on, so if we read back from destination then this transform is not
desired.
