/** Test for SMIL values that are context-sensitive **/
/* See bugs 533291 and 562815.
The format of each test is basically:
1) create some animated and frozen state
2) test the animated values
3) change the context
4) test that context-sensitive animation values have changed
Ideally, after changing the context (3), the animated state would instantly
update. However, this is not currently the case for many situations.
For CSS properties we have bug 545282 - In animations involving 'inherit'
/ 'currentColor', changes to inherited value / 'color' don't show up in
animated value immediately
For SVG lengths we have bug 508206 - Relative units used in
animation don't update immediately
(There are a few of todo_is's in the following tests so that if those bugs
are ever resolved we'll know to update this test case accordingly.)
So in between (3) and (4) we force a sample. This is currently done by
calling SVGSVGElement.setCurrentTime with the same current time which has the
side effect of forcing a sample.
What we *are* testing is that we're not too zealous with caching animation
values whilst in the frozen state. Normally we'd say, "Hey, we're frozen,
let's just use the same animation result as last time" but for some
context-sensitive animation values that doesn't work.
