// Hence, we are returning getInsets() from getBorderInsets().
// A better way would be to create two methods: one for excluded space and one for included space and implement as per convenience.
// Yet another idea: check if RImgControl really needs to sub-class RUIControl or it can directly sub-class BaseElementRenderable.
