LoadPlugin
==========
.. function:: LoadPlugin(string path, bint altsearchpath = False)
:module: std
Load a native VapourSynth plugin. If successful, the loaded plugin's
functions will end up in their own namespace.
Returns an error if a plugin with the same identifier or namespace already
has been loaded. This is to prevent naming collisions or multiple versions
of the same plugin being loaded at once.
Plugins are normally loaded with a very specific search order for
dependencies. Setting *altsearchpath* modifies this behavior to also
include dlls in the PATH.
Beware of Python's escape character, this will fail::
LoadPlugin(path='c:\plugins\filter.dll')
Correct ways::
LoadPlugin(path='c:/plugins/filter.dll')
LoadPlugin(path=r'c:\plugins\filter.dll')
LoadPlugin(path='c:\\plugins\\filter.dll')
