Log:
debian/patches/097_mouse_zaxis_mapping_pushes_up_buttons.diff: add Bartosz
Zapalowski's patch for supporting wheel mice with large numbers of
buttons; the ZAxisMapping option "pushes up" the other buttons so that
the mouse behaves sanely. This addresses problems with how the X server
parses wheel data from at least some devices that use the ExplorerPS/2
protocol. (Closes: #166550)
