comparison vamp-sdk/hostext/PluginWrapper.cpp @ 61:97c5ac99d725 host-factory-stuff

* install hostext headers to vamp-sdk/hostext/ rather than vamp-sdk/
* adjust timestamps in input-domain adapter so as to centre them on block
  as required by Plugin documentation
* better handling for frequency-domain plugins that want non-power-of-two
  blocksizes (can't handle them, but at least try offering them a power-of-two
  alternative)
* couple of Plugin doc additions
* make PluginLoader capable of returning ready-wrapped plugins
