37 ** now abstracted into __INTERNAL_APPROPRIATENESS_CHECK(). When we

41 ** At least for X & GTK redraw_frame_toolbars() might end up getting

|
|
|
43 ** the __INTERNAL_MAPPED_P(f) macro, that should return 0 if we should
|
|
|
44 ** not draw the toolbars yet. When we add new window systems that use
|
|
|
45 ** this code, we should add a new case here, if they need it.

46 **
|

47 ** When clearing the toolbar, it is nice to flush the drawing queue.
