STR #1681: On WIN32 WM_PAINT messages, FLTK would first render the damaged area and then set the area as valid again. While this is mostly fine on single CPU machines, multi-CPU machines may re-invalidate areas that are currently drawn, resulting in unrendered strips when another window was moved quickly across an FLTK window during its redraw phase.
The new implementation validates the damaged area as quickly as possible, allowing new damage requests to be handled correctly, even while we are still redrawing the same damaged area.
