[truetype] Some variable renamings. Too much local variables holding different structures were called `metrics'. * src/truetype/ttdriver.c (tt_size_select): s/metrics/size_metrics/. * src/truetype/ttgload.c (tt_get_metrics_incr_overrids, compute_glyph_metrics): s/metrics/incr_metrics/. (load_sbit_image): s/metrics/sbit_metrics/. * src/truetype/ttobjs.c (tt_size_run_fpgm): s/metrics/size_metrics/. (tt_size_init_bytecode): s/metrics/tt_metrics/.
