Image scaling example for DMDK

-------------------------------------------------

NOTES:
0) This is a functional but incomplete example for scaling functions running on a DMDK.
1) You'll need to install a DMDK to compile and run the code.
2) A minimal set of required files is 
   scale_horz_h.asm: horizontal scaling
   scale_vert_h.asm: vertical scaling
   filt_gen.c: filter coefficient generator
3) To learn how to use the scaling functions, please see scale_2d_yc_boub_buf.c
   which performs scaling on a 2D YCbCr input using EDMA.
4) To lear how to generate filter coefficients, please see main() in video_rgb.c
