Everyone,

I've made a new release of our libtheora reference implementation. This
draws a line under all the development since alpha 4 before we start
merging in the optimization work people have been doing. It also
contains a fix for two serious bugs (one an encoding error, one a
segfault) so we recommend everyone upgrade. The release is source and
binary compatible with 1.0 alpha 4.

Thanks to everyone whose work made this release possible!

Change summary: (libtheora-1.0alpha5 released 2005 August 20)

 * Fixed bitrate management bugs that caused popping and encode
   errors
 * Fixed a crash problem with the theora_state internals not
   being intialized properly.
 * new utility function:
   - theora_granule_shift()
 * dump_video example now makes YUV4MPEG files by default, so
   the results can be fed back to encoder_example and similar
   tools. The old behavior is restored through the '-r' switch.
 * ./configure now prints a summary
 * simple unit test of the comment api under 'make check'
 * misc code cleanup, warning and leak fixes

Cheers,
 -r
