Subject: pointerA11yTimeout: Fade the pie timer in
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~827^2^2~31
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=2c4df6abcf1142fada6069b40d16e951f7c1e63d;p=gnome-shell.git

pointerA11yTimeout: Fade the pie timer in

Fade the pie timer in using a duration of 1/4 of the timeout and a
EASE_IN_QUAD animation. This significantly reduces flickering of the pie
timer while moving the cursor and makes the timer less distracting.
