Actually, looking at this again, I don't think it is valid to call
fl_read_image() at that point in your code, as you do not know what
the current rendering context is...
You really ought to only call fl_read_image() in your widget's draw()
method, as that is the only place you can be sure the graphics
context is valid.
You can probably fake it in this case though, by calling
win->make_current();
just immediately before you call fl_read_image() and all *should* be
well. Probably... On most systems, most of the time...
Worth a try at any rate.
