CVSROOT: /cvs
Module name: XF4
Changes by: ottocvs.openbsd.org 2006/02/03 04:06:32
Modified files:
xc/programs/Xserver/hw/xfree86/common: xf86Xinput.c
Log message:
A high resolution device that's moving fast can potentially generate
an int overflow, making dx*dx+dy*dy negative. Now pow(negative,
non-integer) yields NaN, so you loose. Use fp math to avoid that.
looks resonable millert ok matthieu
