- use the same formula for calculating 3DMidTex offsets as the renderer when per-sidedef scaling is used.

Browse source 
This reuses the FTexCoordInfo class the hardware renderer had been using to calculate wall texture offsetting.
The software renderers still need this sorted out to bring them in line with the rest of the code, though, but they do not have this code sufficiently well organized to make this a straightforward task.
