cacheAsBitmap / generateTexture offset sprite positions

[fyyyyy]

This is an underlying PIXI issue i believe. However its good to notify in the docs that those methods cacheAsBitmap / generateTexture are offsetting sprite positions. The reason is that transparent pixels around graphics are cut automatically, and therefore the sprite positions get shifted. This happens since 2.3 up to 2.8.1

So the docs should give a warning i believe.

I've noticed this with graphics.generateTexture().

It happens with group.cacheAsBitmap = true also?

I havent tried with a group but it happens with sprites that have children.
I have seen bug reports of this happening with groups.
