PhyreEngine3.8 MSAA resolution

There is something wrong in PhyreEngine 3.8 to fullfill MSAA, actually, I think it is eqaa

You have to merge the codes from PhyreEngine 3.9. Thank God they fixed it in 3.9.

A depth target is redefined in it is scope every time!!

 

============

有关phyreengine里面那个针对msaa的resolve.fp我感觉就是最后加起来的那步

在eqaa的算法中，根据权重对同一个像素的不同ps加起来

我觉得resolve做的就是这步

它用一个fmask标记出这些，权重。。大概已经传了
