Artur Wieczorek a29815e19a Allow turning on/off opacity selector in wxColourDialog (wxOSX)
This feature to show/hide alpha values and opacity selector (slider) is
already implemented under wxGTK and for generic wxColourDialog.
For the sake of backward compatibility, this feature is enabled here by
default (through the corresponding property of wxColourData).
