[Visualpython-users] minor fixes to the current beta version

[Bruce S. <Bru...@nc...>]

Two minor fixes which apply to the current beta version and which of 
course will be incorporated in the next release:

1) Attached is a corrected ui.py (now in CVS) which replaces the one 
which in Windows is found at C:\Python25\Lib\site-packages\visual\ui.py. 
This fixes a problem with the lighting of controls (buttons, sliders) 
but more generally fixes a problem with any older program that specifies 
special lighting. The bug was that in creating a display, default lights 
were set without checking to see whether the program was specifying its 
own lights.

2) Peter Borcherds kindly points out that in the summary of new features 
for the beta version the sample code for making a simple checkerboard 
texture contains mistakes in specifying the numerical type of arrays, 
now that we're using numpy rather than Numeric. This has been corrected 
in the documentation at vpython.org > Recent developments.
