|
This test guards against culling behind filters that change opacity. The red box is given
|
|
an opacity of 0% with a CSS filter, so only the green box behind it should be visible.
|
|
This version of the test causes part of the boxes to be out of view, testing the interaction
|
|
between their visible region with culling.
