Fixes to syborg-graphicswrapper.vcproj These changes allow syborg-graphicswrapper to link against the hostthreadadapter and khronosapiwrapper libraries built by the graphics.simulator component. The .vcproj file uses relative paths, which requires that the following three packages are laid out as follows: os/ graphics adapt/ graphics.simulator qemu

class Delegator:

    # The cache is only used to be able to change delegates!

    def __init__(self, delegate=None):
        self.delegate = delegate
        self.__cache = {}

    def __getattr__(self, name):
        attr = getattr(self.delegate, name) # May raise AttributeError
        setattr(self, name, attr)
        self.__cache[name] = attr
        return attr

    def resetcache(self):
        for key in self.__cache.keys():
            try:
                delattr(self, key)
            except AttributeError:
                pass
        self.__cache.clear()
