[GRASSGUI] opacityDialog

[Martin Landa]

Hi Michael,

maybe it would be better to use for changing layer opacity level
instead of wx.SpinCtrl *wx.Slider*. The attached patch shows one of
the way (not so elegant) how to do it.

Popup Menu -> "Change Opacity" -> opacity ialog

What do you think?

Martin
