[visionegg] release 1.1 imminent - call for testing

Hi all,

It's been 2 years since the last official Vision Egg release, and in
that time numpy has gained near-universal support as the array package
for Python. Thanks to initial work and prodding by Martin Spacek, the VE
now uses numpy at its core and does not require the older array packages
(although it is still compatible with them). With this in mind and with
several other changes to the code base (see below), it's time to release
a new version of the Vision Egg. I have uploaded a release candidate
source package to http://pypi.python.org/pypi/visionegg , and I would
appreciate any testing and feedback before releasing this as the
official 1.1 release. Everything I've tested works for me with this
code, so please report any issues you might have.

Changes for 1.1:
----------------

* Workaround PyOpenGL 3.0.0a and 3.0.0b1 bug in glLoadMatrixf().

* Fix SphereMap.AzElGrid() to properly draw iso elevation and azimuth
  lines at specified intervals.

* Change to use numpy at the core instead of Numeric. (Require numpy,
  no longer require Numeric.)

* Require setuptools

* No longer supporting Python 2.2

* Update Textures to accept numpy arrays as data source (by Martin Spacek)

* Update to work with PyOpenGL 3

* Changes so to reflect standard idioms on Python project layouts:
    - src/ directory renamed to VisionEgg/
         (but .c files need to be moved back to src/)
    - use 'package_data' distutils argument
  This enables setuptools to work with the Vision Egg.

* QuickTime movies work in Windows (need to check on OS X).

* FilledCircle stimulus is now anti-aliased. Thanks to Peter Jurica
  and Gijs Plomp.

* Added demo/texture3D_alpha.py
