Evas filters: Add render test cases with pixel verification
Force render into an Ecore_Evas, and check that the pixels are valid: - Not all transparent (can't really happen) - Not all black (since there's a black rect behind the text) - All valid premultiplied values (A >= R,G,B) Yes, it's a bit slow. But at least it really checks something :)
