    RenderWare(tm) v3.1 Demonstration Program (sky): Alpha-Blending
--------------------------------------------------------------------------

PURPOSE

The BLENDING example illustrates alpha-blending using a pair of 2D 
immediate objects which overlap in screen-space. The first object is
rendered on the far clip-plane with source blend function rwBLENDONE and
destination blend function rwBLENDZERO. This overwrites the frame-buffer 
with RGBA values equal to color of the first object. The second object
is then rendered on the near clip-plane using blend functions which can
be chosen from the menu.

The RGBA values of the source and destination can also be specified from 
the menu. Component values are defined in the range 0.0 -- 1.0 and 
converted internally to the range 0 -- 255.
