BitmapMaterialTools.mirrorBitmapX() draws on top of flipped bitmap #247

What steps will reproduce the problem?

You will only notice this if you use a transparent material,
eg transparent png with text.

BitmapMaterialTools.mirrorBitmapX(yourBitmap.bitmapData);
will flip the image but you can still see the unflipped image beneath.

Adding
bitmap.fillRect(bitmap.rect, 0);
before
bitmap.draw(tmp, tmp.transform.matrix);

In both mirrorBitmapX() and mirrorBitmapY() 
solves the problem.
