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

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

47 ** called before we are completely initialized. To avoid this, we use
|
|
|
48 ** the __INTERNAL_MAPPED_P(f) macro, that should return 0 if we should
|
|
|
49 ** not draw the toolbars yet. When we add new window systems that use
|
|
|
50 ** this code, we should add a new case here, if they need it.

51 **
|
