-        It returns a shader with a reference count of 1.
-        The caller should decrement the shader's reference count when done with the shader.
-        It is an error for count to be < 2.
-        @param  diffuse     the diffuse bitmap
-        @param  normal      the normal map
-        @param  light       the light applied to the normal map
-        @param  ambient     the linear (unpremul) ambient light color. Range is 0..1/channel.
-        @param  localMatrix the matrix mapping the textures to the dest rect

-        NULL will be returned if:
-            either 'diffuse' or 'normal' are empty
-            either 'diffuse' or 'normal' are too big (> 65535 on a side)
-            'diffuse' and 'normal' aren't the same size
-
-        The lighting equation is currently:
-            result = LightColor * DiffuseColor * (Normal * LightDir) + AmbientColor
-
-        The normal map is currently assumed to be an 8888 image where the normal at a texel
-        is retrieved by:
-            N.x = R-127;
-            N.y = G-127;
-            N.z = B-127;
-            N.normalize();
-        The +Z axis is thus encoded in RGB as (127, 127, 255) while the -Z axis is
-        (127, 127, 0).
