Sets the multiplier value to be applied when in additive blending mode.
void setAdditiveBlendingAlpha(float value);
This value will be multiplied with the colour of rendered primitives before they are applied
as an additive blend (when in additive blending mode).
The value set by this method is persistent across transitions into additive blending mode,
and across rendering frames (across calls to iTestBed::update()).
