[visionegg] Re: fixation viewport

Yes, that would be nice, but how about answering my question?  Do I
have to search all over the python world to find this too?  I have
started using python, after many years of working with perl and
recently matlab.  I have some idea of object oriented programming and
I realise that this particular problem seems so simple to solve.  I
expected to read the class documentation, find the right
variable/parameter to set and then just set it.  However, it was not
solved in 5 minutes and I'm not sure what the next step is.  Maybe I
need to learn more about the python class and parameter setting
process.  I was wondering if I have to use create_screen() rather than
get_default_screen() just so I can set the screen background color.  I
figure that screen background color should be a dynamic variable, so I
was hoping that screen.bgcolor was something I could set.  Not so
simple, Mr Magoo :-o
