if fltk::Window::draw_overlay() changes the transformation matrix and does not restore it, the effect is OS-specific: in Linux it's OK, but in win32 the transformation preserves between calls. Documentation says "Your draw() function must put the transformation and clipping back, or nasty things will happen!". IMHO it would be good if the same thing was explicitly said in draw_overlay() documentation, or the effect be the same on different systems, to avoid confusion. | |
