Instead of calling ctx->redraw() to redraw the window, call ctx->set_dirty().
The FlowCtx will redraw the window at the end of the event_handler if any event has marked it as dirty.
If you really need to redraw the window NOW (ex. after a timer triggered event),
call ctx->set_dirty followed by ctx->redraw_if_dirty().

not big enough to jusify 6 versions of every script and makefile.
We don't need 71500 lines of "copy-paste" code to handle those small differences.
