Fix "linear_sweep(..., texture=..., scale=..., twist=...)".

Browse Source 
The commit 'Fix "linear_sweep(..., texture=..., scale=...)" was not
enough.  This one fixes linear_sweep(..., texture=...) when scale
and/or twist parameters are specified.

Code to reproduce the fixed issue:

  linear_sweep(ellipse(d = [5, 10]), 5, twist = 45, texture = "bricks", scale = 0.5);
