NAME
     mlib_VideoColorRGBXint_to_ABGRint - convert RGBX interleaved
     to ABGR interleaved

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     void mlib_VideoColorRGBXint_to_ABGRint(mlib_u32 *ABGR,
          const mlib_u32 *RGBX, const mlib_u8 *A_array,
          mlib_u8 A_const, mlib_s32 w,
          mlib_s32 h, mlib_s32 dlb,
          mlib_s32 slb, mlib_s32 alb);


DESCRIPTION
     The interleaved RGBX stream and the alpha  values  are  com-
     bined  into  an interleaved A, B, G, R output stream. Within
     each 32-bit input pixel, the component ordering is  R  (bits
     31-24),  G  (bits 23-16), and B (bits 15-8). Within each 32-
     bit output pixel, the component bordering is A (bits 31-24),
     B  (bits  23-16), G (bits 15-8), and R (bits 7-0). The alpha
     values for this function work in the following  fashion:  if
     A_array   is  not  NULL,  the  values  are  taken  from  the
     corresponding locations in the alpha array, otherwise a con-
     stant  alpha  value,  specified by A_const, is store in each
     output pixel. Each element in the alpha array is an unsigned
     byte.  w  and  h  define the dimensions of the region of the
     buffers to be processed. The linebyte parameters are used to
     advance the data pointers for each of the buffers.

PARAMETERS
     The function takes the following arguments:

     ABGR       Pointer to output buffer (word-aligned).


     RGBX       Pointer to input buffer (word-aligned).


     A_array    Pointer to array of alpha values (byte-aligned).


     A_const    Constant alpha value (range = 0..255).


     w          Image width in pixels.


     h          Image height in lines.
