Both units are the 40250 bodies; only the PDT-stream draw becomes
UIRenderAddImage (with the rendering mode). SCREEN/COLOR_DODGE were packed as
0x28 (INVDESTALPHA+ONE); 40250 uses INVDESTCOLOR+ONE (0x2A). OnIsType calls the
base OnIsType instead of 40250's recursing IsType. port.grp_resource covers the
quads, UVs, colour and blend mode.
