- Added per-tier texture scaling with these new UDMF sidedef properties:

Browse source 
* scalex_top
  * scaley_top
  * scalex_mid
  * scaley_mid
  * scalex_bottom
  * scalex_bottom
- Added sidedef versions of the linedef flags wrapmidtex and clipmidtex (via
  UDMF; names are the same). If the flag is set on the line, it applies to
  both sides. Otherwise, each side can control them individually.
