[AGG] Add more pixel tests for out-of-bounds coordinate lines
Add minimal test cases for line misrenderings when the coordinates are
out-of-bounds. The bounds are [-32000, 32000]. The expected result is
the Skia rendering, while the buggy AGG rendering result is suppressed.
bug_1846.in has been renamed to bug_1972_1.in so that the similar line
tests are grouped together.
