The implementor of that function must do whatever is necessary to cause

OK, I can fake that easily enough, I don't think I can actually ask it
to request a refresh. Refresh events themselves probably don't need
me to run through the entire redraw process - AmigaOS tends to handle
refreshes itself for the most part, and I'm writing directly to the
window (for now), so I shouldn't need to worry about that yet.
I think I'm still missing something important. The only plotters that
are called are:
clip 0 0 800 600
clg ffffff
My redraw code looks like this (I've hardcoded the window to 800x600
temporarily hence the values below):
struct content *c;
c = g->bw->current_content;
current_redraw_browser = g->bw;
content_redraw(c, 0, 0, 800, 600, 0, 0, 800, 600, g->bw->scale,
0xFFFFFF);
current_redraw_browser = NULL;
That seems reasonable enough. I assume your plotting functions are
returning true on success and false on failure? Redraw will give up if
there's a problem.
