Re:Draw a transparent Gif to a Canvas

I've had some problems with that in the past. While I don't remember
all the specifics, I have the following in my code:

TGIFImage *g = static_cast<TGIFImage *>
(FImg->Picture->Graphic);

// This call is necessary to make a transparent GIF pick up a
new
// background
g->StopDraw();
