The function creates a new style on the heap every time it's called. 
That style is then allocated to the widget, so it must be persistent. 
This will cause a lot of memory to be used... unless you can absolutely 
guarantee that the "gtk_style_detach" call results in the old style 
being free'd. The documentation only says it "may" result in it being 
"unrealised".
