Add a "Composited preview" option to all transform-grid tools, which displays the transform preview as part of the image composition (i.e., as it would actually look when applying the transformation, keeping the layer at the right position in the stack, and with the right layer mode), instead of using an overlay. This option is off by default, since it's generally slower to render than an overlay, due to the lack of mipmap rendering. We're also still using an overlay when transfoming a selection, and not a whole layer.
