| 16 * The output color of this effect is a modulation of the input color and a sample from a texture. | |
| 17 * It allows explicit specification of the filtering and wrap modes (GrTextureParams). It can use | |
| 18 * local coords, positions, or a custom vertex attribute as input texture coords. The input coords | |
| 19 * can have a matrix applied in the VS in both the local and position cases but not with a custom | |
| 20 * attribute coords at this time. It will add a varying to input interpolate texture coords to the | |
