This change detects what area of a layer was drawn into and generates a mesh to match this area exactly. This can be used to avoid blending empty pixels when the layer is composited. This change also adds proper layers support to lines rendering and implements layers composition in a more readable way. Change-Id: I4a5588b98b19bd66891ebdc39631b193c5e31999
