Bug in GUI text wordwrap logic

[historic_bruno]

The GUI engine has a bug in the wordwrap logic when a text box is not left-aligned. As you can see in the following example with center-aligned text:

Produced by this simple code:

messageBox(500, 300,
            "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 abcdefghijklmnopqrstuvwxyz0123456789",
            "Test", 2);

This is most noticeable when arbitrary length strings (such as file paths) are displayed in the UI, so we can't necessarily compensate by making the text elements wider.

Sounds like duplicate of #723.

Resolution of #723 will fix this issue also.
