This may come back in the future to deduplicate some gfx code, but SCI32 had two different inlined ways of doing coordinate conversions with different rounding methods, so CoordAdjuster32 didn't get used when the graphics system was rewritten. At the moment, SCI32 code uses the mulru/mulinc methods from helper.h for scaling up/down coordinates.
