Original commit message from CVS:
Rewrote much of videoscale. Now handles most common YUV formats
as well as 32 and 24 bit RGB. Only handles "nearest" scaling.
Original commit message from CVS:
* removal of //-style comments
* don't link plugins to core libs -- the versioning is done internally to the plugins with the plugin_info struct,
and symbol resolution is lazy, so we can always know if a plugin can be loaded by the plugin_info data. in theory.
