blendFunc
uniform ivec4 blendFunc;
The alpha blending function multipliers for the current program, as described in blend.<program>. The components of the vector store the following:
x: source RGBy: destination RGBz: source Alphaw: destination Alpha
The value stored in each component is one of the following hardcoded integer values (see LWJGL docs):
| Blend Value | Integer Value |

GL_ZERO | 0 |
GL_ONE | 1 |
GL_SRC_COLOR | 768 |
GL_ONE_MINUS_SRC_COLOR | 769 |
GL_SRC_ALPHA | 770 |
GL_ONE_MINUS_SRC_ALPHA | 771 |
