Encapsulates OpenGL blend/transparency state.
Blending combines incoming fragment with a fragment already present in the target buffer.
OpenGL 1.1 supports following source and destination blending factors: GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_DST_ALPHA, GL_ONE_MINUS_DST_ALPHA, GL_ZERO, GL_ONE.
Moreover, there are three source-only blending factors: GL_DST_COLOR, GL_ONE_MINUS_DST_COLOR, GL_SRC_ALPHA_SATURATE and two destination-only blending factors: GL_SRC_COLOR, GL_ONE_MINUS_SRC_COLOR. OpenGL 1.4 allowed to use these five blending factors as both - source and destination blending factors.
Following four source and destination blending factors were added by Imaging subset of OpenGL 1.2 and made mandatory by OpenGL 1.4: GL_CONSTANT_COLOR, GL_ONE_MINUS_CONSTANT_COLOR, GL_CONSTANT_ALPHA, GL_ONE_MINUS_CONSTANT_ALPHA
OpenGL 1.4 further provides glBlendFuncSeparate (promoted from GL_EXT_blend_func_separate). It makes possible to set blending functions for RGB and Alpha separately. Before, it was possible to set just one blending function for RGBA.
