//  Class:    Frame
//
//  Purpose:  Represents a captured video frame.
//
//  Comments: Frames are received from FrameCap in Windows
//            bitmap format as a "raw" (uncompressed) rgb bitmap.
//            Pixels are concatenated row by row, starting from
//            the bottom of the image. There are three bytes per
//            pixel. First byte is blue, second green, and third
//            is red. This format is passed unaltered.
