* Toolkit implementation (100%): https://github.com/sugarlabs/sugar-toolkit-gtk3/pull/213

* Frame and Home view (100%): https://github.com/sugarlabs/sugar/pull/505 Frame and homeview are a good spot for tick based animation as we are not cpu bound to open the frame or change views - the animation can take up 100% cpu and all will be fine

* Pulsing icon (~~20%~~): https://github.com/sugarlabs/sugar/pull/513 Opening an activity is a cpu bound task, so this is probably the wrong space for animations that steal all of the cpu.

* Pulsing icon (NO-GO): https://github.com/sugarlabs/sugar/pull/513 Opening an activity is a cpu bound task, so this is probably the wrong space for animations that steal all of the cpu. This patch TRIPLES activity start times on the XO4.

~~Doesn't break anything~~.

Animation consumers need to add the "widget=x" when creating an animator so they can have the tick callback attached.

~~Animation consumers need to add the "widget=x" when creating an animator so they can have the tick callback attached~~.

Consumers who don't are not effected.

==UI Design==

~~Some animations (aka. plusing icon) look completely different when they are actually smooth.~~

None

== How To Test ==

~~1. Apply the patches <~~https://github.com/sugarlabs/sugar-toolkit-gtk3/pull/~~213> and <https://github.com/sugarlabs/sugar/pull/505>~~

https://github.com/sugarlabs/sugar-toolkit-gtk3/pull/258#issuecomment-145695297

~~2. Open the frame and notice the smoothness~~

~~3. Press F6 over and over again to enjoy all the frames in the animation~~

~~4. Change between home views (F1-F3) to enjoy the smoothness of the animating size of the xo~~-~~person~~
