Bug #9316260 The GL specification indicates that deleting a bound texture has the side effect of binding the default texture (name=0). This change replaces all calls to glDeleteTextures() by Caches::deleteTexture() to properly keep track of texture bindings. Change-Id: Ifbc60ef433e0f9776a668dd5bd5f0adbc65a77a0
