| 14 | * This test exercises bug 1719. An anti-aliased blurred path is rendered through a soft clip. On |
| 15 | * the GPU a scratch texture was used to hold the original path mask as well as the blurred path |
| 16 | * result. The same texture is then incorrectly used to generate the soft clip mask for the draw. |
| 17 | * Thus the same texture is used for both the blur mask and soft mask in a single draw. |
| 18 | * |
| 19 | * The correct image should look like a thin stroked round rect. |
