Idea: transition callers to this, so we can later typedef SkColorFilter and SkShader to the same thing.

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