dix: Hush an almost certainly bogus warning
../dix/getevents.c: In function ‘transformAbsolute’: ../dix/getevents.c:1195:28: warning: ‘oy’ may be used uninitialized in this function [-Wmaybe-uninitialized] struct pixman_f_vector p = {.v = {*x, *y, 1} }; ^ ../dix/getevents.c:1234:22: note: ‘oy’ was declared here double x, y, ox, oy; ^~ This one is truly special. Even though both ox and oy are set and read along the same paths, only oy is marked for this warning! Initializing just oy = 0.0 fixes it entirely, but let's not make a weird thing weirder.
