Try loading the dissect package (just released) in J6 and J8, and see
the differences. In particular, look at the sentence display at the top
of the graphics window - in J8 it shows rectangle boundaries.
Also, see how the display of shape and rank information (above the
results) seems to be uncentered in the rectangle.
Also, the Arial font seems to size differently in J8 than in J6.
Do you agree that the graphics should look the same between J6 and J8?
If so, I will work on characterizing the differences.
Remember to upgrade your grid before installing dissect.

gl2 for J8 has a number of incompatibilities with J6, and also just
seems a pixel off in some cases. Since there will be graphics
applications used on both J6 and J8 for a while yet, it seems to me
that J8 ought to do things the J6 way when there is no reason not to.
What I have found so far:
0. glarc seems to go CW around the ellipse; J6 went CCW
1. drawing abutting rectangles, with the same color and no pen,
should leave a smooth field; in J8 there are visible joints
2. drawing text inside a box, the text seems to be shifted one pixel
to the left. Or maybe the box is one pixel to the right.
3. When I draw a box with a pen just inside the wdclip rectangle,
the right and bottom are chopped off. In J6 the cliprect was already
one row/col too short; j8 is even shorter. This may be related to
item 2.
This weekend I will release a graphics application for J6 and J8. It
formats properly on J6, and exhibits pixel problems on J8.
