- Removed all the unsigned char garbage from the API
- Updated types in lv2.h to be non-machine-dependant (removed unsigned long in favour of uint32_t) - Updated schema - Updated example plugin to work with the above (partially) git-svn-id: http://svn.drobilla.net/lad/libslv2@101 a436a847-0d15-0410-975c-d299462d15a1
