35 of 0.0 is used for fully transparent objects, while an alpha value
39 OpenGL defines alpha as a component of the vertex color state.
40 Whenever a color is set, the alpha component is set along with the
43 modifying the color of each vertex, replacing the old alpha
44 component with the new alpha component. This can be very expensive
48 This extension defines a new global alpha attribute that can be
49 used to specify an alpha factor that is independent from the alpha
50 component of the color value. The global alpha factor is
51 multiplied by the fragment's alpha value after primitive
