AGC: color format 7 (COLOR_11_11_10 float) with COMP_SWAP 0 is refused #9083

What

A title (PPSA12361) stops on current main with AGC graphics: unsupported color format 7 number type 7 component swap 0 (std::runtime_error, then SIGABRT), run_090532.err lines 2661-2663 of the run that found it. DecodeColorFormat accepts format 7 only with the reversed component order (COMP_SWAP 2) since #7207; the title binds the standard order.

Format 7 keeps its 10-bit component in the low bits of the word. With the reversed order that is blue (#7207). The standard order puts red in the first slot, which is also how Mesa pairs SWAP_STD with COLOR_10_11_11 for R11G11B10_FLOAT (src/amd/common/ac_formats.c), so with COMP_SWAP 0 red lands in the low 10 bits and blue in the high 11. Not measured on the console.
