GL_warp2Avi 2 GB file-size limit

Found by trial and error that the GL_warp2Avi has a 2 GB file size limit for both input and output avi files. This is due to the limitations of the legacy video for windows code used. The limits are discussed at

Because of this, I could not use huffyuv codec for clips longer than 30 seconds or so. My workaround was to use x264vfw for high quality input and output avi files with small size.

Note: Workaround for input file limits - using virtualdub frameserver.
