the main reason for doing this is so that we can have access to informations about a texture (like its dimension) close to where we generate and use shaders in ES 2.0. Previously, there wasn't any way to get to a texture's size from a RenderEngine implementation. Bug: 8679321 Change-Id: I388b338a70d07e3e8177dde248710ea1e4c82dff
