This implementation is not 100% engine accurate, but it is more accurate than what was there, and hopefully the differences between this and the engine code are merely cosmetic. The known (intentional) differences are: 1. Uses ScummVM rects inside the engine code, converting to/from SCI rects on the kernel edges and when scaling 2. Fewer side effects when performing operations that *should* have been pure from the start (like text dimension calculation). Still not side-effect-free, but at least things like colours and alignment do not need to be reset every time a measurement is taken, unlike in the actual engine. Editor controls and some other kBitmap code are temporarily disabled as a result of changes to GfxText32 until they can be updated to be engine-accurate.
