+Comments:
+A class to load and decompress DXT textures to 32-bit raw image data format.
+.RAW output files can be loaded into photoshop by specifying the resolution 
+and 4 color channels of 8-bit, interleaved.
+
+A few approaches to block decompression are in place and a simple code timing
+function is called.  Output of timing test is saved to a local .txt file.
+
+TiZ: some modification to adapt the code to run under PS2.
