image.

The Center Image button is badly named, and this has caused you to misinterpret the expected result.

Expected Result: when user clicks the Center Image button, system is to scroll the image so that the centre of the image is on the centre of the screen. The image is the entire drawing surface, not only what has been marked on the surface by the user.

The use-case of the Center Image button is after a change of canvas scroll position, such as after a zoom. Try this; draw something in the top right of the canvas, place the cursor over it, then use the Ctrl-Z accelerator for Zoom In, repeat this until no further zoom is possible, observe the position of the canvas, then Center Image.

Perhaps the Center Image button should be insensitive when the image is already centred.

Perhaps the Center Image button should be renamed Center Canvas.

Hi, thanks for the excellently written bug report and the clarification and suggestions by quozl.

I'll try to improve this confusing button in the next version.
