Window resizes in wrong direction if mouse cursor did not move

[nephele]

If starting a resize without having moved the mouse beforehand the window will always start resizing from the left, this is somewhat annoying to me as my mouse sometimes drops right clicks intermitently, and i usually resize from the right.

To reproduce:

• hold alt gr with cursor on the right side of the window
• Start resizing with mouse2
• Stop resizing; keep holding alt gr and don't move mouse cursor after stopping
• Press mouse2 to resize again, it now resizes the left border instead of the right one
