test caes of sterically intersecting sibling semi-transparent layers

Because TextureMapperLayer sorts siblings by z order (in TextureMapperLayer::sortByZOrder),
sibling semi-transparent layers are blended as expected in most cases.

However, if sibling semi-transparent layers are sterically intersecting,
some semi-transparent layers can hide background.

To solve this issue perfectly, TextureMapper needs OIT support.
