[Qgis-developer] only zoom with mouse wheel if no keyboard modifier pressed

[Borys Jurgiel]

Hi all,

I often regret the mouse wheel is wasted, as it could have different functions 
with Shift or Ctrl pressed. Here is a small patch to intercept the wheel if 
any keyboard modifier is pressed and pass it to QgsMapTool:

Is there any objection to block the zooming when a modifier is pressed?
