/**
* Native bindings to the EXT_blend_func_extended extension.
*
* This extension provides an ES version of the ARB_blend_func_extended functionality.
*
* Traditional OpenGL includes fixed-function blending that combines source colors with the existing content of a render buffer in a variety of ways. A
* number of extensions have enhanced this functionality by adding further sources of blending weights and methods to combine them. However, the inputs to
* the fixed-function blending units are constrained to a source color (as output from fragment shading), destination color (as the current content of the
* frame buffer) or constants that may be used in their place.
*
* This extension adds new blending functions whereby a fragment shader may output two colors, one of which is treated as the source color, and the other
* used as a blending factor for either source or destination colors. Furthermore, this extension increases orthogonality by allowing the
* SRC_ALPHA_SATURATE function to be used as the destination weight.
*
* Because of the limitations of the OpenGL ES 2.0 shading language, new built-in variables (gl_SecondaryFragColorEXT, gl_SecondaryFragDataEXT) are added
* to the ES 1.00 shading language rather than introduce more complex features for user-defined fragment outputs. Because such built-in variable are
* deprecated in ES 3.0, these variables are NOT available in the OpenGL ES 3.xx shading language verisons.
