There should be two hourglass shapes drawn inside the window
|
|
called "Polygon Fill Test". The outline should be blue
|
|
and the interior should be green and there should be no gaps
|
|
between the filled interior and the outline nor should the green
|
|
filler spill outside the blue outline. You may need
|
|
to use a screen magnifier to inspect the smaller shape
|
|
on the left to verify that there are no gaps.
|

If both polygons painted correctly press "Pass" otherwise press "Fail".
