#492 Cancel magnetism under Linux

[Paul]

Quote from help:
To help you drawing parallel walls, the angle of walls is a multiple of 15° by default. You may cancel this magnetism by disabling magnetism in the preferences pane or while drawing, by holding down the Alt key under Windows, the cmd key under Mac OS X or the Shift + Alt keys under Linux

Stand: Ubuntu Linux Desktop 11.10 x64
Steps:

1. Draw walls;
2. Hold down Shift + Alt keys.

Result:
Magnetism is not canceled. It will be canceled when user presses Alt+Shift keys, and it will be activated when user presses Shift+Alt keys

Could you check that it works better in version 4.5?
