We will delve into our investigation of drawing surfaces, by rewriting the 'drawingareas.rb' program from chapter 11, turning the plain single colour background surface into a background adorned with an arbitrary image you load from an image file on your disk.
-Needless to say, the main feature in this new version of the above drawing program from paragraph 11.1 is the dynamically re-sizable background, responding to users' changing the parent window containing the drawable area with any image you choose as the background. However, even more valuable aspect of this new 'drwar01-rsizble-stretched-pxb-bg.rb' program here is its exposure of the differences between the background surface and the drawings or 2D images user draws, paints or copies onto the background surface.

In reality this distinction is rather fuzzy, namely, anything you draw or otherwise paint to the background can become a new background, nevertheless, in this, and in the next program, we are going to keep one and the same background (with its original image) throughout the duration of any one program execution.
