58 Changes from version 3.1: 58 Changes from version 3.1:
59 Changed handling of button 3 press and release events.
60 WARNING: This could be a breaking change for apps handling
61 mouse button 3. Windows, Mac and GTK now pass button 3 as
62 the mask (value 4) instead of the button number (value 3).
63 OS/2 and the related motion event passed buttons as a mask.
64 In these value 3 is buttons 1 and 2 together. Button
65 press and release events are only for a single button...
66 so this would never happen allowing value 3 for button 3.
67 To allow the same code to work for button presses and motion
68 events, I am standardizing on using the masks for both.
69 If you use button 3 press/release, please audit code for 3.2.
