Minimalistic grouping strategy that splits decals into opaque and transparent ones enabling and disabling blending as needed.
Opaque decals are rendered first (decal color is ignored in opacity check).
<br/>
Use this strategy only if the vast majority of your decals are opaque and the few transparent ones are unlikely to overlap.
</p>
<p>
Can produce invisible artifacts when transparent decals overlap each other.

States (* = any, EV = entry value - same as value before flush):
