BGE: new bge.logic.Render() to perform render w/o logic step.

This function works only if python has control:
1. add scene custom property, call it __main__
2. give it string value as the name of a text block
3. code game loop in python in text block. Example:

import bge

bge.logic.setUseExternalClock(True)
t = 0.0;
scene = bge.logic.getCurrentScene()
cam = scene.cameras["Camera"]
cam.setViewport(120,120,370,370)
while not bge.logic.NextFrame():
cam.useViewport = True
# second render with viewport enable, clock time unchanged
bge.logic.Render()
# advance animation for next frame
t += 0.02
bge.logic.setClockTime(t)
cam.useViewport = False
