Non-animated GIF handling less than ideal

[fire-eggs]

Still finding this code to be extremely useful.

I've used the patch which changes fl_images_core.cxx, in fl_check_images, so that GIF files are loaded as Fl_Anim_GIF_Image instances.

But this leads to the following convolution when it comes time to draw, in order to handle non-animated GIFs:

		if (animgif_->is_animated())
		{
			animgif_->draw(xoff, yoff, xsize, ysize);
		}
		else
		{
			animgif_->Fl_Pixmap::draw(xoff, yoff, xsize, ysize);
		}

It "works" but requires "knowing" that Fl_Anim_GIF_Image is derived from Fl_Pixmap!

I'd prefer that animgif_->draw() would work for both animated and still GIFs. I'm not smart enough yet to quite understand the implications of this comment in the Fl_Anim_GIF_Image code:

    // Note: should the base class be called here?
    //       If it is, then the copy() method must also
    //       copy the base image!
//    Inherited::draw(x_, y_, w_, h_, cx_, cy_);

Advice, fixes appreciated.

Hm, its a long time since I was active in this project...
Could you please give me a complete example code, so that I can see clearer, what your issue is?

Trying to create a sample program, I'm reminded about how much I've learned over the last few months.

This particular section of code is, in fact, dealing with the rare case that Fl_Anim_GIF_Image has failed to load a valid GIF file, in which case I've used Fl_GIF_Image as a fallback. The bug here is that Fl_GIF_Image fails to draw correctly. Not your bug!

Closing this issue and submitting an issue for the animated GIF file that Fl_Anim_GIF_Image fails to load.
