[visionegg] Re: mirroring a text strimulus?

Hi Gary,

I just added such functionality including a demo script. The new demo
can be seen at
http://visionegg.org/trac/browser/trunk/visionegg/demo/texture_as_numpy_array.py


This will require the latest VE from svn, however. If that's a pain, you
should just be able to take the latest VisionEgg/Textures.py from the
source repository and overwrite the version in your installation. Test
it with the new demo script.
