draft patch

The patch tries to catch a flickering bug at animation tests by using JavaScript.
Added function to WTR that checks the color code of a given pixel in the given fractions of time. If the corresponding pixel's color code difference is below a given threshold in every cases, the test passes. 
This timing and color code checking is test specific: timing and color checking need to be customized for every tests.

Any opinion or advice is appreciated.
