UltimateZoneBuilder/Source/Plugins/BuilderModes/VisualModes/BaseVisualThing.cs
MaxED 52ab917179 Visual Mode, UDMF: Change texture scale actions now try to change scale by one texture/sprite pixel at a time. Action info now also shows scaled texture/sprite size.
Info panels: float values are now formatted regardless of current CultureInfo (e.g. decimal separator is now always dot). Also, they are no longer clamped to 2 decimal places.
Updated ZDoom_ACS.cfg.
