Title: * change default opacity value

If the default opaticy value is 0 and you don't change it, when you want to set another color by calling setColor(const Color3B&), you must call setOpacity(GLubyte) also to set another non-zero opaticy value, otherwise, you still have a black LayerColor. Sometime, it can make someone confused.
