-When the value A_COLOR is selected as the destination alpha blending factor,
-the source pixel color is used as the destination blending factor. When the
-value A_COLOR is selected as the source alpha blending factor, the destination
-pixel color is used as the source blending factor. When the value A_SAMECOLOR
-is selected as the destination alpha blending factor, the destination pixel
-color is used as the destination blending factor. When the value A_SAMECOLOR
-is selected as the source alpha blending factor, the source pixel color is
-used as the source blending factor. Note also that the alpha blending
-function 0xf (A_COLORBEFOREFOG/ASATURATE) is different depending upon whether
-it is being used as a source or destination alpha blending function. When the
-value 0xf is selected as the destination alpha blending factor, the source
-color before the fog unit ("unfogged" color) is used as the destination
-blending factor -- this alpha blending function is useful for multi-pass
-rendering with atmospheric effects. When the value 0xf is selected as the
-source alpha blending factor, the alpha-saturate anti-aliasing algorithm is
-selected -- this MIN function performs polygonal anti-aliasing for polygons
-which are drawn front-to-back.
