Alternative pertification.

[Carvercarver1]

Some graphic cards deal poorly with the pertification application, same for forming the ice cube on the ice dragon freeze effect (same for ice weapons).
E.g, instead of getting correct texture change and etc, it only displays the uncracked stone layer first (same for ice cube), but should there be any changes to it like player using pickaxe to break the statue or ice cube stating to melt and crack - stone texture not only will be gone, but the entity itself either becomes invisible completely or visible in it's first form but standing completely still and without stone texture (and in case of cave troll - even returning to it's idle animations).

Some alternative methods rendering are required in cases where stone breaking texture layer is not rendered due to graphics card issue, or user having integrated one. Or any other unforseen issue.
