remove code to deal with non-normalized texture coordinates for tex rect targets (swtcl tex coord translation stage, tcl tex matrix adaption) and use the chip's native handling of such coords instead (!!!). Seems noone noticed those bits in the se_coord_fmt reg, even though it works fairly similar to r200 (except it's set per-unit and always active, so only enable it for texture rectangles).
