TerrainPaintCommand

Remarks

The sibling of TerrainStrokeCommand, over a different record. A sculpt stroke holds one layer's deltas; a paint stroke holds every layer's weights, because painting one lowers the rest proportionally — see TerrainWeightStroke.

⚠ Merging is off, for [§ D11]'s reason. Two strokes are two undos. What merges is inside the stroke: a drag is one record being extended, so by the time one of these exists the merging has already happened.
