[Bf-python] setRenderBorder() patch for BF Blend CVS

[Campbell Barton]

Here is the patch, it works fine by all accounts and documentation is 
aded too, Needs a Window.Redraw() to show the chatnge, that or 
mousewheel on the camera view- Dont consider this a bug, many blender 
funcs are like this.

Use this python code to test it.


import Blender
from Blender import *
from Blender.Scene import Render

scn = Scene.GetCurrent()
context = scn.getRenderingContext()

context.enableBorderRender(1)
context.setRenderBorder(0.3, 0.4, 0.5, 0.7)
