LoadAllPlugins
==============
.. function:: LoadAllPlugins(string path)
:module: std
Loads all native VapourSynth plugins found in the
specified *path*. Plugins that fail to load are
silently skipped.
Beware of Python's escape character, this will fail::
LoadPlugin(path='c:\plugins')
Correct ways::
LoadPlugin(path='c:/plugins')
LoadPlugin(path=r'c:\plugins')
LoadPlugin(path='c:\\plugins\\')
