possible bug string format %G IM 6.8.6.8 Q16

[fmw42]

The documentation on http://www.imagemagick.org/script/escape.php shows:

%G image size ( = %wx%h )
%P page (canvas) size ( = %Wx%H )

But %G reports the same values as %P which are the page size and the the image size

convert -size 500x500 xc:black -size 100x100 xc:white \
-geometry +200+300 -compose over -composite -trim -format "%G" info:
500x500

convert -size 500x500 xc:black -size 100x100 xc:white \
-geometry +200+300 -compose over -composite -trim -format "%P" info:
500x500

convert -size 500x500 xc:black -size 100x100 xc:white \
-geometry +200+300 -compose over -composite -trim -format "%wx%h" info:
100x100

%G is the original image size, when its first read, before any resizes.

I will modify the string formats documentation.
