[PyQt] glGetFloatv crashes application

Hi,

Yes, I can see that could be a problem.

Using a predefined list of lengths could be a solution. I think that's 
how PyOpenGL does it. There's a list of all constants for example here:

https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/glGet.xml

However, there are a few hundreds of them!
