Why not use renderscript support library?

[MohMah]

Hi, I saw you had this code in PeekAndPop.java class

        if (Build.VERSION.SDK_INT >= 17 && blurBackground)
            blurBackground();
        else if (Build.VERSION.SDK_INT < 17 && blurBackground)
            Log.e("PeekAndPop", "Unable to blur background, device version below 17");

why not use renderscript support library and import android.support.v8.renderscript.* instead of android.renderscript.* so it works on apis lower than 17?
