Source Blending Values

When a drawing engine's transparency blending function is set to the value kQABlend_OpenGL , the state variable kQATagGL_BlendSrc must be set to a value to indicate the red, green, blue, and alpha source blending factors. You can use these constants to define the source blending factors.

#define kQAGL_SourceBlend_XXX                       0
