This script tests that system theming works for launched applications.

Testing that changing the theme is done as follows:

  * launch application
  * take a screenshot (1)
  * change theme
  * take a screenshot (2)
  * change theme back to original theme
  * take a screenshot (3)
  * make sure that 1 and 2 differ and that 1 and 3 are the same

Testing that application specific theming is done using an application
which has application specific theming and application specific svg
graphics:

  * start application without launcher
  * take screenshot of themed widgets (1)
  * start application with launcher
  * take screenshot of themed widgets (2)
  * verify that (1) and (2) are equal

Testing that booster-m is restarted after theme change
  
  * get the pid of booster-m (1)
  * launch application
  * change theme
  * Again get the new pid of booster-m (2)
  * Make sure 1 and 2 differ.
