Revision:	1.34
Committed:	Tue Apr 3 00:21:37 2007 UTC (17 years, 2 months ago) by root
Branch:	MAIN
Changes since 1.33:	+3 -0 lines
Log Message:	- fix ber encoding - reduce image checksum length to 6 bytes (from 16) - implement fx packet, which reduces face overhead to amortised 10/12 bytes per face instead of 21/32 bytes and allows an unlimited number of faces instead of 2**16.
