Update to 1.0beta2:

libtheora 1.0beta2 (2007 October 12)

 - Fix a crash bug on char-is-unsigned architectures (PowerPC)
 - Fix a buffer sizing issue that caused rare encoder crashes
 - Fix a buffer alignment issue
 - Build fixes for MingW32, MSVC
 - Improved format documentation.

libtheora 1.0beta1 (2007 September 22)

 - Granulepos scheme modified to match other codecs. This bumps
   the bitstream revision to 3.2.1. Bitstreams marked 3.2.0 are
   handled correctly by this decoder. Older decoders will show
   a one frame sync error in the less noticable direction.

It also includes the changes done for alpha8, which was short lived and
is only interesting for historical reasons:

libtheora 1.0alpha8 (2007 September 18)

 - Switch to new spec compliant decoder from theora-exp branch.
   Written by Dr. Timothy Terriberry.
 - Add support to the encoder for using quantization settings
   provided by the application.
 - more assembly optimizations
