Hi,

I have attached a fix for the fringe issue. The images were reversed, the
background was not transparent (which the rendering code assumed it was),
and finally, all images were mirror flipped left-to-right...

I have attached a patch for this, please try it out. If possible, try to
check if this causes some other image-related problems which I haven't
thought of.

(I will clean up the trace code before I commit it.)

I don't think it really worked for fullheight frames. When enabling the
tool bar in a maximized frame it looked OK at first glance. However, below
the screen, the window stretched out about three text lines, but due to the
bug Keith reported, the text grid was restricted with the same amount. The
effect was that it only looked like it worked.

Now, when enabling tool-bar mode in a fullheight frames, after Keiths bug
was fixed, the frame stretches below the screen. It's a bit unfortunate,
but it will be a lot of work to do anything about it -- given how the tool
bar is currently implemented.

full-screen in terms of height.

I can see the same effect here. I have only tried this with a fullheight
frame, in which case it worked. I will take a look at it and try to figure
out what the difference between the fullheight and maximized cases.

Ps. I will be away over the weekend -- hopefully I will be able to answer
mail but not do any Emacs core work.
