[Bf-taskforce25] const & Context!

[Ton Roosendaal]

Hi,

Especially drawing calls get const Context as arg for functions, but 
this messes up in cases... I tried to fix things for it, but in two 
cases there were severe issues;

- Python code, it uses C all over, should this become all const?
- the armature retarget/sketch code, to me it seems the C is used only 
to pass on a Scene pointer even...

I think we should be careful in passing on C for functions... 
especially once code isn't "Context sensitive" anymore, it can just use 
the actual args.

We should also pin down how/when C is 'const'.
