In a previous thread that I started about positioning of LABELs, Thomas Bonfort said, "I'd be in favor of having a way to specify the anchor point, either by fixing it on 0,0 , or by specifying it alongside the symbol, eg ANCHORPOINT 0.3 2". I agree that this would be good for symbols too but it may present a problem with scaled symbols, especially TTF. If it's not a fixed size then how can an anchor point be specified?
Regarding ANCHORPOINT (CENTER / ORIGIN) and scaled symbols: For vector and ellipse symbols it should be specified in the coordinate system that is used in the symbol definition. For pixmaps, one could use the pixel coordinates of the original image (perhaps having (0,0) at the centre of the image, and y increasing upwards?). For truetype symbols, one could perhaps use a font coordinate system that is size-independent?
