GTK: do not compose rendered geometry with an alpha buffer. 

The somewhat confusingly named set_has_alpha() function does not
affect whether alpha can be used during rendering to the area.
Rather, it affects whether alpha will be used when composing
the contents of the area with the window underneath it.
