commit 9b88b5dce5327cbd13ea05de949c502fe41f91f7
Author: Andrea Canciani <ranma42 at gmail.com>

test: add degenerate gradient and single stop tests
Add tests for degeneratate linear gradients (with start point equal
to the end point), degenerate radial gradients (start radius and end
radius equal to zero, same start and end circle) and gradients (both
linear and radial) with just a single stop.
