blendFunciOES method
The blendFunciOES() method of the OES_draw_buffers_indexed WebGL
extension defines which function is used when blending pixels for a
particular draw buffer.
See OES_draw_buffers_indexed.blendFuncSeparateiOES for setting RGB and alpha components separately and WebGLRenderingContext.blendFunc for the WebGL 1 version of this method.
Implementation
external void blendFunciOES(GLuint buf, GLenum src, GLenum dst);
