Pure additive color blending (src * 1 + dst) whose color factors match Babylon.js
BLENDMODE_ONEONE / ALPHA_ONEONE. This generic descriptor uses one / one
alpha factors; exact particle OneOne instead uses zero / one. Unlike
spriteBlendAdditive, source RGB is not weighted by alpha. This is useful
for particle textures that encode their falloff directly in RGB.
