SF: Add ability to get basic geometry

For computing the layer visibility, CompositionEngine will need to get
basic geometry state for every layer, without getting everything. Add a
new request type for the basic geometry state, and modify the existing
code in computeVisibleRegions to use it rather than accessing directly
through the front-end layer pointer.
