a694f30: Add more alpha gradient test cases
* Add a vertical linear gradient. This bypasses AGG and uses a faster
code path, which works.
* Add gradients drawn in a ClipToPicture() context. This uses an
* unpacked scanline rasterizer, which works.
This hints to the problem being the use of a packed scanline rasterizer,
with agg gradients touching the alpha channel.
