2x Shrink SSE algorithm

The uploaded presentation describes the SSE implementation of imge 2x shrink, when one pixel contains 4 bytes: 3 color components R, G & B, and 4th components - weight A.

Speed-up (comparing with serial code) is 4.6 for Merom platform, ~7 on Penryn platform.

Please, find attached:

1. PowerPoint presentation, describing this algorithm.
2. ZIP file containing C code project implementation, included into simple benchmarking application. The project is built for MS VisStudio-2005.

Command line doesn't have any arguments - application name only.
